FIELD OF THE INVENTION
The present invention relates to an inexpensive system for the production of
energy. More particularly, the present invention relates to a clean energy
generating device which maximizes power generation efficiency 5 and power
generation output and generates high output electricity from low input supply and
system and methods related thereto.
BACKGROUND OF THE INVENTION
10
As is generally known, the world has been facing a great energy crisis. This crisis
has a tendency to worsen in the coming years due to the shortage of fossil fuels,
bringing, consequently, an enormous problem and concern for future generations.
There are other sources of energy generation such as solar, wind, nuclear etc.
15 However, such conventional sources of energy are also inadequate to meet the
demand and suffer from one or more problems. For example, conventional solar
power generation systems convert only about thirty percent of the Sun's energy
into electricity. Much of the signal from sunlight is lost in inefficient transfer and
conversion of electron charge within a static solar cell. Moreover, conventional
20 solar power production is limited to only daylight hours. As a result, conventional
solar power generation provides only about one-tenth of one percent of all
electricity used in the world. Instead, most electricity is produced by fossil fuel run
systems and hydroelectric plants both of which produce undesirable
environmentally unfriendly waste and cause damage to the environment.
25
Further, there are a variety of conventional devices for generating electrical power
from vibrations, oscillations or other mechanical motions. These devices include
passive devices i.e. inductive devices, capacitive devices, and active devices i.e.
piezoelectric devices.
30
Passive devices or components do not generate energy, but can store it or
dissipate it. However, active device or components are those having an ability to
electrically control electron flow (electricity controlling electricity).
3
Piezoelectric materials generate a voltage when they are stressed along a
preferred direction. Thus, mechanical energy can be converted to electrical
energy through the use of a dielectric elastomer generator. The dielectric
elastomer is susceptible to various modes of failure, however, including 5 electrical
breakdown, electro-mechanical instability, loss of tension, and rupture by overstretching.
Capacitive devices are, likewise, disadvantageous because they require an
10 auxiliary electrical supply. The available electric power density to capacitive
devices is also limited.
Devices that use electromagnetic transduction or induction schemes have
generally shown higher power densities when compared to electrostatic and
15 piezoelectric approaches. Various energy generating methods exist for capturing
and storing energy from normally occurring environmental sources, such as
thermal, solar, mechanical or vibrational.
For many years electric power generator engineering focused on different
20 configurations of moving of coils past magnets or magnets past coils. Since the
idea has worked, however inefficiently, the way by which electricity was produced
did not change for many years or could not achieve generating electricity
efficiently.
25 Therefore, the search for alternatives capable of meeting the ever-increasing
demand becomes increasingly necessary, and yet taking into consideration that
there will be an increasing contingent population, to supply everyone satisfactorily
without causing damage to the environment.
30 On the other hand, it is also vital that the solutions must be always focused on
finding options that are preferably clean, which do not emit gases, waste,
substances or contaminant particles in the air.
4
The challenges are immense, besides the need to search for alternative energies
capable of supplying what the populations need, reducing contaminants and
solutions should find an ideal balance between the nature and all living beings.
So, this invention is worked out for a new and better energy generating device
which generate high output electricity from low input supply 5 overcoming the
above-discussed disadvantages.

fossil fuels and contaminants which harm the environment, contribute to the

warming. The subject technology may produce clean electricity at all hours

SUMMARY OF THE INVENTION
5
The present invention seeks to provide a new power generation system, the
related device and method adaptable to maximize power generation efficiency
which allows a much greater portion of the magnetic flux with high magnitude of
magnetic flux density to be converted to electrical power. This is accomplished by
10 utilizing a plurality of mutually spaced magnets to move together relative to at
least one winding, and preferably a plurality of windings, so that alternating
increasing and decreasing magnetic fields are established to generate high output
electricity from low input supply. Electrical power is generated in each of said
windings by a time varying magnetic flux created by moving said magnets across
15 said windings or alternatively said windings across said magnets when the shaft is
rotating.
Various embodiments of the subject invention, thus, relate to enhancing the
performance of the electromagnetic induction for various magnet and coil
20 structures by, for example, strengthening the magnetic field created by the moving
magnet and/or controlling the position of the magnetic field created by the moving
magnet. Thus, maximizing power generation efficiency and power generation
output is achieved by the change in a magnetic circuitous permeability path for
magnetic lines of force that move through magnets, windings to induce, by
25 Faraday's Law of Electromotive Induction.
The simplified governing equation of Faraday for induction voltage known to the
person skilled in the art is:
30
Where is the electromotive force (EMF) i.e. voltage and ΦB is the magnetic flux
in that a voltage is induced in a circuit whenever relative motion exists between a
7
conductor and a magnetic field and that the magnitude of this EMF i.e. voltage is
proportional to the rate of change of the flux. The direction of the electromotive
force is given by Lenz’s law which is indicated by minus sign. In other words,
electromagnetic induction is the process of using magnetic fields to produce EMF
i.e. voltage, and a current in 5 a closed circuit.
The amount of EMF i.e. voltage which can be induced into the windings/coils
using just magnetism is based on the following factors a) increasing the number of
turns of wire in the winding/coil i.e. if there are ten turns in the winding/coil there
10 will be ten times more induced EMF i.e. voltage than in one piece of wire, b)
increasing the speed of the relative motion between the coil and the magnet i.e. if
the same coil of wire passed through the same magnetic field but its speed or
velocity is increased, the wire will cut the lines of magnetic flux at a faster rate so
more induced EMF i.e. voltage would be produced, and c) increasing the strength
15 of the magnetic field i.e. if the same coil of wire is moved at the same speed
through a stronger magnetic field, there will be more EMP i.e. voltage produced
because there are more lines of magnetic flux to cut.
Thus, one aspect of the present invention relates to a clean energy generating
20 device which generate high output electricity from low input supply. The device of
the invention to generate high output electricity from low input supply, comprises:
a casing with an inner wall having two opposite side open ends; a rotor shaft

one side of the rotor shaft; a second winding provided on another stator in
between a third and a fourth bearing secured on other side of the rotor shaft; a
pair of input wires connecting the first winding to an external input power source;
30 and a pair of output wires connecting the second winding, combines the winding
outputs to produce a highly increased energy output.

In yet other embodiment(s), a device to generate high output electricity from low
input supply is provided, the device comprising: a set of plurality of magnets
secured on a fixed portion in parallel on one side of a casing on the opposite sides
of a rotor shaft; a plurality of windings constituting winding portions on a stator
secured on the rotor shaft creating a movable portion between 5 the magnets;
another set of plurality of magnets constituting magnet portions secured
alternately in parallel in other side of the casing on the rotor shaft wherein the
magnets arranged in between a winding and a winding having minimal space
there between, the windings secured to an inner wall(s) of the casing; a fan is
10 arranged in between bearings in order to maintain the heat and temperature of the
device while running; a pair of input wires connecting the first windings to an
external input power source; and a pair of output wires connecting the winding to
a circuit that combines the winding outputs to produce a net energy output.
15 In yet another embodiment, an energy generating device to generate high output
electricity from low input supply is provided the device comprising: a casing and a
rotor shaft arranged therein in a rotatable manner; a set of plurality of magnets
secured in an inner peripheral surface of the casing in one side thereof; a stator
secured around one side of the rotor shaft in a manner to allow synchronous
20 rotation; a set of plurality of windings wound around the stator and another set of
plurality of magnets secured in-between the windings; another stator secured
around the rotor shaft in a manner to allow synchronous rotation in other side of
the casing, wherein the stator has an inner core constituting plurality of windings;
a set of plurality of magnets secured on the stator over the inner core; wherein the
25 stator being secured to the rotor shaft is within a housing rotatably connected to
the rotor shaft and wherein a plurality of windings are provided on the inner
surface of the housing.
In a further embodiment, an energy generating device to generate high output
30 electricity from low input supply is provided, the device comprising: a casing and a
rotor shaft arranged therein in a rotatable manner; a stator secured around the
rotor shaft in a manner to allow synchronous rotation within the casing, wherein
the stator has an inner core constituting plurality of windings; a set of plurality of
9
magnets secured on the stator over the inner core; wherein the stator being
secured to the rotor shaft is within a housing rotatably connected to the rotor shaft
and wherein a plurality of windings are provided on the inner surface of the
housing; a pulley and belt drive running through kinetic energy providing input
power source to the device; and a pair of output wires connecting 5 the winding to a
circuit that combines the winding outputs to produce a net energy output.
Another aspect of the present invention relates to a method of constructing an
energy generating device, the method comprising the steps of: securing a set of
10 bearings, including first, second, third and fourth bearings on a rotor shaft;
wrapping around a first winding on a stator in between first and second bearings;
wrapping around a second winding on another stator in between third and fourth
bearings; securing plurality of magnets in an inner wall of a casing; inserting the
rotor shaft in the casing; securing input and output connections on both sides of
15 the rotor shaft; and sealing the two side openings of the casing by two side
covers. The said energy generating device generate high output electricity from
low input supply.
Yet another aspect of the present invention relates to a system comprising said
20 clean energy generating device which generate high output electricity from low
input supply.
A plurality of magnets and windings, having substantially equal and/or unequal
lengths and spacings along a common axis, can be employed in various
25 embodiments of the invention. If the magnets are oriented in magnetic opposition
to each other and generate similar fields, the component of the fields parallel to
the axis will cancel at locations between successive magnets, thereby producing
large magnetic field differentials as the magnets move relative to the windings or
alternatively the windings move relative to the magnets and a consequent high
30 voltage output. The outputs from the individual windings can be combined to
produce a net generator output.
10
Magnets can be, for example, linear, cylindrical, helical, or cage-like. One or more
windings or coils can be positioned with respect to the magnets such that as the
magnet(s) roll, electric current is created in the one or more coils via the changing
magnetic fields. Other shaped magnets can be used, such as magnets having
ellipsoidal cross-sections or other cross-sectional shapes that 5 allow rotational
movement. For embodiments utilizing multiple magnets, spacers can be used to
maintain a separation between magnets. The placement and spacing can be
selected for power optimization or maximization. The magnets and windings of the
invention are so formed and arranged as to be relatively movable, for converting
10 kinetic energy to electric energy by electromagnetic induction.
The disclosure of the invention embodies to include one or more converters and
related means to convert AC to DC or DC to AC at output and/or input ends as per
the need in various embodiments discussed herein.
15
The rotor is a moving component of an electromagnetic system in the electric
motor, electric generator, or alternator. Its rotation is due to the interaction
between the windings and magnetic fields which produces a torque around the
rotor's axis.
20
The various embodiments of the invention take advantage of the higher magnetic
flux created by a cylindrical magnet and enjoy benefits of a spherical outer
topology. However, it is not limited to only cylindrical shape, various other shapes
are also possible to achieve the same result. Multiple magnets can be embedded
25 in a non-magnetic casing to create optimal magnetic field patterns. The design of
the casing may be optimized for magnetic field strengthening and directing
purpose.
The utility of the present invention includes but is not limited to electrical power
30 generation.

10
To reach the objects stated above, referring to FIGS. 1 and 2, the present
invention provides a high-efficiency energy generating device 10 which has a
casing 12 made of a non-conducting and/or conducting, non-magnetic and/or
magnetic material such as plastic, aluminum, stainless steel, metal, glass etc.
15 Preferably, the casing 12 is tubular or cylindrical in shape. However, the casing 12
can have other shapes such as square, oval, rectangular or the like, etc. The
casing 12 comprises a supporting body and having, preferably, an inner cylindrical
cavity defined therein having inner wall 38 and two open ends 28, 30. The casing
further comprises two side covers 34, 36 for the open ends 28, 30 having outlets
20 40 for input wires 42 and output wires 58.
A set of plurality of magnets for example, a set of first 16 and second 18 magnet,
preferably, having equal lengths and dimension are secured in parallel on an inner
wall of the casing 12 on the opposite sides of a non-magnetic rotor shaft 14. The
25 length and dimension of the first 16 and second 18 magnets may vary in
alternative embodiments. Another set of plurality of magnets for example, a set of
third 20 and fourth 22 magnet having equal lengths and dimension are secured in
parallel on an inner wall of the casing 12 on the opposite sides of the rotor shaft
14. Likewise, the length and dimension of the third 20 and fourth 22 magnets may
30 vary in alternative embodiments. The magnets are not connected, but are kept
apart from each other. The rotor shaft 14 is arranged substantially in center of the
casing 12 by movably securing the rotor shaft 12 in the coupling holes centrally
formed on the inner sides of the two covers 34, 36.
15
The magnets 16, 18, 20, 22 are securely attached to the inner wall 38 of the
casing 12. The magnets 16, 18, 20, 22 can be securely attached to the casing
12 as part of an integrated manufacturing process of the casing 12. The magnets
16, 18, 20, 22 can also be welded, soldered, bonded or glued 5 or secured to the
inner wall 38 of the casing 12 by any combination of two or more such joining
methods or permanently fixed/attached by other known means, methods or
materials. The magnets 16, 18, 20, 22 used are permanent unipolar magnets. In
alternative embodiments, bipolar magnets can also be used.
10
A first winding 24 is provided on a stator in between a first 44 and a second 46
bearing secured on one side of the rotor shaft 14. The first winding 24 is arranged
in between the first magnet 16 and the second magnet 18 having a space 32 inbetween.
A second winding 26 is provided on another stator in between a third 48
15 and a fourth 50 bearing secured on other side of the rotor shaft 14. The second
winding 26 is arranged in between the third 20 and fourth 22 magnet having a
space 32 in-between. The first 24 and second 26 windings have spacing 52 along
a common axis defined by the rotor shaft 14. The first 24 and second 26 windings
are arranged apart from each other. The bearings 44, 46, 48, 50 has a through
20 hole centrally formed therethrough to receive the rotor shaft 14. The windings 24,
26 can be made of copper, aluminum or other metallic conductor wire that are
wrapped around the rotor shaft 14 in a known manner.
The stator is an unmoving component of an electrical machine that’s going around
25 the rotor. It’s derived from the word ‘’stationary’’ as the ‘’stator’’ implies. It contains
the windings and provides mechanical support and protection for the motor.
The rotor shaft 14 is mounted on the casing through the holes of the four bearings
44, 46, 48, 50 and onto the coupling holes centrally formed on the inner sides of
30 the two covers 34, 36.
16
The first winding 24 has a length equal to the length of the first magnet 16 and the
second magnet 18. Likewise, the second winding 26 has a length equal to the
length of the third 20 and fourth 22 magnet.
Thus, the first 16 and second 18 magnets and first winding 24 5 are preferably of
equal length and separated by equal gaps/spacings. Likewise, the third 20 and
fourth 22 magnets and second winding 26 are preferably of equal length and
separated by equal gaps/spacings. In one embodiment, the length of the magnets
16, 18 is not equal to the length of the magnets 20, 22. In alternative
10 embodiments, if desired equal lengths of the magnets and windings and/or
spacings in between them could be used.
The first winding 24 is connected to carbon brushes 54 and sliprings 56, which is
further connected by a pair of input wires 42 to an external input power source,
15 which may include solar, wind or any other power source. The second winding 26
is connected to carbon brushes 54 and sliprings 56, which is further connected to
output wires 58. Because the carbon brush 54 causes wear and tear by its friction
with winding 24 and winding 26, the slipring 56 is provided for pushing the carbon
brush 54 to move and keeping close contact between the carbon brush 54 and the
20 winding 24 and winding 26 on the rotor shaft 14. Other means and methods to
connect the input 42 and output 58 wires with the rotor shaft 14 can also be used
and some of such alternative means and methods are discussed in alternative
embodiments disclosed herein.
25 The power-generating magnets 16, 18, 20, 22 are arranged in a circular form
about the central rotor shaft 14 on the inner circumferential surface therein such
that upon rotation of the rotor shaft 14, the first 24 and second 26 windings also
rotate about the central rotor shaft 14. In one embodiment, the rotation of the
windings 24, 26 takes place in a clock-wise direction. In the alternative
30 embodiment, the rotation of the windings 24, 26 takes place in an anti-clock-wise
direction. The rotation creates magnetic flux created by the magnets 16, 18, 20,
22 and windings 24, 26 which results in enhancing the output power by at least
two to three times the input of power for example the input of 12 volts is converted
17
into output of 36 volts. The magnetic flux can be increased by increasing the
rotation of the rotor shaft 14. More rotation of the rotor shaft 14 will generate more
power, for example the input of 12 volts may be converted into output of 36 or 48
volts or more depending on the rotation speed of the rotor shaft 14. The generated
electric power may be routed to a grid system or storage system 5 for further use.
Figures 3 to 7 are schematic sectional views of various alternative embodiments
of an energy generating device of FIG. 2 having modifications with different
positions of the magnets and spacings there-between according to the principles
10 of the present invention. The device of these embodiments utilizes the
components and functions in the above-discussed manner which maximizes
power generation efficiency and power generation output and generates high
output electricity from low input supply.
15 The number/quantity of magnets 16, 18, 20, 22 is merely exemplary, and the
number of magnets 16, 18, 20, 22 may be any number represented by 2n where
‘n’ is a positive integer.
Referring now to another embodiment of the energy generating device 210 as
20 shown in Fig. 8, a set of plurality of magnets for example, a set of a magnet 216
and magnet 218, preferably, having equal length and dimension are secured on
the fixed portion in parallel on one side 259 of a casing 212 on the opposite sides
of a rotor shaft 214. The length and dimension of the magnets 216 and 218 may
vary in alternative embodiments. A plurality of windings constituting winding
25 portions 262 on a stator are secured on the rotor shaft 214 creating a movable
portion between the magnets 216 and 218. The windings 262 has a length equal
to the length of the magnets 216 and 218. However, it is possible that varied
length of the windings 262 with respect to the length of the magnets 216, 218 can
be used in alternative embodiments.
30
While the magnet portions are provided on the fixed portion of the casing and the
windings are provided on the movable portion to constitute the electromagnetic
induction type power generating portion in the aforementioned embodiment, the
18
present invention is not restricted to this but the magnet portions and the windings
may alternatively be provided on the movable portion and the fixed portion
respectively. Effects similar to the above can be attained also in this case. Similar
arrangement can be done with respect to all other embodiments of the invention.
5
Further, a set of plurality of magnets 220, 222 constituting magnet portions having
pole faces (north pole 220a and south pole 220b) and (north pole 222a and south
pole 222b) respectively, preferably, having equal lengths and dimension are
secured alternately in parallel in other side 260 of the casing 212 on a non10
magnetic rotor shaft 214. The pole faces of the magnets constituting the magnet
portions 220, 222 are so alternately arranged that magnetic flux changes can be
increased with respect to rotation/vibration, whereby the quantity of power
generated in electromagnetic induction can be increased. In the rotor shaft 214 of
this configuration, wherein the magnets 220, 222 are arranged in the order of N,
15 S, N, S, . . . . With such a configuration, an output of approximately twice or more
than that of the energy generating device as illustrated in FIG. 2 can be obtained.
The length and dimension of the magnets 220 and 222 may vary in alternative
embodiments. The rotor shaft 214 is arranged substantially in center of the casing
20 212 by movably securing the rotor shaft 214 in the coupling holes centrally formed
on the inner sides of the two covers 234, 236. The magnets 220, 222 can be
securely attached to the rotor shaft 214 in the casing 212 as part of an integrated
manufacturing process of the casing 212. The magnets 220, 222 can also be
welded, soldered, bonded or glued or secured to the rotor shaft 212 by any such
25 method or combination of two or more such joining methods or permanently
fixed/attached by other known means, methods or materials. The magnets 220,
222 used are permanent bipolar magnets. In alternative embodiments, unipolar
magnets can also be used.
30 The magnets 220, 222 are arranged in between a winding 224 and a winding 226
having minimal space 232 there between. The windings 224, 226 are secured to
the walls of the casing 212. In alternative embodiments, the windings 224, 226
can be arranged with spacing between the magnets 220, 222.
19
The rotor shaft 214 is mounted on the casing 212 through the holes of the four
bearings 244, 246, 248, 250 and onto the coupling holes centrally formed on the
inner sides of the two covers 234, 236. The bearings 244, 246, 248, 250 have a
through hole centrally formed therethrough to securely receive the 5 rotor shaft 214.
The windings 224, 226 can be made of copper, aluminum or other metallic
conductor wire. A fan 264 is arranged in between bearings 246 and 248 in order
to maintain the heat and temperature of the device 210 while running. The device
10, 210, 310, 410, 510 can be provided with a fan in the similar manner in all the
10 disclosed embodiments. The air flow by the fan 264 is particularly valuable in
keeping the temperature caused due to rotation as low as possible under all
conditions of operation. This enhances the output of the energy generating device
and also minimizes the risk of demagnetization at high temperatures.
15 The device 210 is connected to a pair of input wires 242 to an external input
power source, which may include solar, wind, water or any other power source
which drives the rotor shaft 214. The input power source can also be Direct
Current (DC) or Alternating Current (AC). The device 210 is further connected to
output wires 258. Input 242 and output 258 wires can be connected to the device
20 210 by means of carbon brushes 254 and sliprings 256. Other means and
methods to connect the input 242 and output 258 wires with the device 210 can
also be used.
The power-generating magnets 216, 218, 220, 222 are arranged in a circular form
25 about the central rotor shaft 214 such that upon rotation of the rotor shaft 214, the
windings 224, 226, 262 also rotate about the central rotor shaft 214. The rotation
of rotor shaft 214 is in a clock-wise direction. In the alternative embodiments, it is
possible to have the rotation of the rotor shaft 214 in an anti-clock-wise direction.
The rotation creates magnetic flux created by the magnets 216, 218, 220, 222 and
30 windings 224, 226, 262 which results in enhancing the output power by at least
two to three times the input of power for example the input of 12 volts is converted
into output of 36 volts. The magnetic flux can be increased by increasing the
rotation of the rotor shaft 214. More rotation of the rotor shaft 214 will generate
20
more power, for example the input of 12 volts may be converted into output of 36
or 48 volts or more depending on the rotation speed of the rotor shaft 214. The
generated electric power may be routed to a grid system or storage system for
further use.

The number/quantity of magnets 216, 218, 220, 222 is merely exemplary, and the
number of magnets 216, 218, 220, 222 may be any number represented by 2n
where ‘n’ is a positive integer.
10 Referring now to yet another embodiment of the energy generating device 310 as
shown in Fig. 9, a set of plurality of magnets for example, a set of a magnet 316
and magnet 318, preferably, having equal length and dimension are secured in
parallel on one side 359 of a casing 312 on the opposite sides of a rotor shaft 314.
It is possible to use varied length and dimension of the magnets 316, 318 in
15 alternative embodiments. A plurality of windings constituting winding portions 362
being wound on a stator are secured on the rotor shaft 314 between the magnets
316, 318. The windings 362 has a length equal to the length of the magnets 316,
318. However, it is possible that varied length of the windings 362 with respect to
the length of the magnets 316, 318 can be used in alternative embodiments.
20
Further, a plurality of magnets 320, 322, 366 constituting magnet portions having
pole faces (north pole 320a and south pole 320b), (north pole 322a and south
pole 322b) and (north pole 366a and south pole 366b) respectively, preferably,
having equal lengths and dimension are secured alternately in parallel in other
25 side 360 of the casing 312 on a non-magnetic rotor shaft 314. The pole faces of
the magnets constituting the magnet portions 320, 322, 366 are so alternately
arranged that magnetic flux changes can be increased with respect to
rotation/vibration, whereby the quantity of power generated in electromagnetic
induction can be increased. In the rotor shaft 314 of this configuration, wherein the
30 magnets 320, 322, 366 are arranged in the order of N, S, N, S, N, S, N, S,. . . With
such a configuration, an output of approximately twice or more than that of the
energy generating device as illustrated in FIG. 2 can be obtained.
21
The length and dimension of the magnets 320, 322, 366 magnets may vary in
alternative embodiments. The rotor shaft 314 is arranged substantially in center of
the casing 312 by movably securing the rotor shaft 314 in the coupling holes
centrally formed on the inner sides of the two covers 334, 336. The magnets 320,
322, 366 can be securely attached to the rotor shaft 234 in the 5 casing 312 as part
of an integrated manufacturing process of the casing 312. The magnets 320, 322,
366 can also be welded, soldered, bonded or glued or secured to the rotor shaft
312 by any such method or combination of two or more such joining methods or
permanently fixed/attached by other known means, methods or materials. The
10 magnets 320, 322, 366 used are permanent bipolar magnets. In alternative
embodiments, unipolar magnets can also be used.
The magnets 320, 322, 366 are arranged in between a winding 324 and a winding
326 having minimal space 332 there between. The windings 324, 326 are secured
15 to the walls of the casing 312 such that the magnets 320, 322, 366 being
connected to carbon brushes 354 and sliprings 356 rotate in between the
windings 324, 326 to create a magnetic flux. In alternative embodiments, the
windings 324, 326 can be arranged with spacing between the magnets 320, 322,
366.
20
The rotor shaft 314 is mounted on the casing 312 through the holes of the four
bearings 344, 346, 348, 350 and onto the coupling holes centrally formed on the
inner sides of the two covers 334, 336. The bearings 344, 346, 348, 350 have a
through hole centrally formed therethrough to securely receive the rotor shaft 314.
25 The windings 324, 326 can be made of copper, aluminum or other metallic
conductor wire. A fan can be arranged in between bearings 346 and 348 in order
to maintain the heat and temperature of the device 310 while running in alternative
embodiments.
30 The device 310 is connected to a pair of input wires 342 which is further
connected to an external input power source. The input power source can also be
Direct Current (DC) or Alternating Current (AC) in other embodiments having
known means and arrangement for such connection. It is possible to have input
power source including solar, wind, water or any other power source. The device
22
310 is further connected to output wires 358. Input 342 and output 358 wires can
be connected to the device 310 by means of carbon brushes 354 and sliprings
356. Other means and methods to connect the input 342 and output 358 wires
with the device 310 can also be used.
5
The magnets 316, 318, 320, 322, 366 are arranged in a circular form about the
central rotor shaft 314 such that upon rotation of the rotor shaft 314, the windings
324, 326, 362 also rotate about the central rotor shaft 314. The rotation of rotor
shaft 314 is in a clock-wise direction. In the alternative embodiments, it is possible
10 to have the rotation of the rotor shaft 314 in an anti-clock-wise direction. The
rotation creates magnetic flux created by the magnets 316, 318, 320, 322, 366
and windings 324, 326, 362 which results in enhancing the output power by at
least two to three times the input of power for example the input of 12 volts is
converted into output of 36 volts. The magnetic flux can be increased by
15 increasing the rotation of the rotor shaft 314. More rotation of the rotor shaft 314
will generate more power, for example the input of 12 volts may be converted into
output of 36 or 48 volts or more depending on the rotation speed of the rotor shaft
314. The generated electric power may be routed to a grid system or storage
system for further use.
20
The number/quantity of magnets 316, 318, 320, 322 is merely exemplary, and the
number of magnets 316, 318, 320, 322 may be any number represented by 2n
where ‘n’ is a positive integer.
25 Referring now to yet another embodiment of the energy generating device 410 as
shown in Fig. 10, a stator 472 is secured around the rotor shaft 414 in a manner to
allow synchronous rotation in the casing 412. The stator 472 has an inner core
478 constituting plurality of windings 424 which include a three-phase winding
wound into the slots as can be seen in Fig. 14. In the alternative embodiments,
30 dual windings (a winding consisting of two separate parts which can be connected
in series or parallel. A set of plurality of magnets 416 are secured on the stator
472 over the inner core. The stator 472 being secured to the rotor shaft 414 is
within a housing 470. A plurality of windings 424 are provided on the inner surface
476 of the housing 470. The housing 470 is rotatably connected to the rotor shaft
23
414 with a spacing 452 from the inner wall of the casing 412. Since the housing
470 is integrally made with the rotor shaft 414, the rotation of rotor shaft 414
causes the housing 470 to rotate around stator 472. Even when the rotor shaft
414 is rotated in the high-rotational speed which generates heat, the possibility of
the energy generating device 410 getting damaged or its lifetime 5 being shortened
is reduced due to the rotor shaft 414 being provided with the housing 470. As well
as the need of carbon brush and sliprings for connection is also removed due to
the provision of housing 470.
10 The set of plurality of magnets 416 have equal lengths and dimension. The length
and dimension of the magnets 416 may vary in alternative embodiments. The
rotor shaft 414 is arranged substantially in center of the casing 412 by movably
securing the rotor shaft 412 in the coupling holes centrally formed on the inner
sides of the two covers 434, 436.
15
The magnets 416 are securely attached to the stator 472. The magnets 416 can
also be welded, soldered, bonded or glued or secured to the stator 472 by any
combination of two or more such joining methods or permanently fixed/attached
by other known means, methods or materials.
20
The stator 472 is provided in between a first 444 and a second 446 bearing
secured on the rotor shaft 414. The bearings 444, 446 have a through hole
centrally formed therethrough to receive the rotor shaft 414. The windings 424 can
be made of copper, aluminum or other metallic conductor wire that are wrapped
25 around the rotor shaft 414 in a known manner or by use of one or more stators.
The rotor shaft 414 is mounted on the casing through the holes of the bearings
444, 446 and onto the coupling holes centrally formed on the sides of the two
covers 434, 436.
30 The rotation of the shaft 414 is accomplished by a pulley 468 and belt drive
running through kinetic energy generated for example, from a water source
providing input power source to the device 410. The input power source can also
be Direct Current (DC) or Alternating Current (AC). It is possible to have input
power source including solar, wind, or any other power source. The other end of
24
the device 410 is further connected to output wires 458 connecting the windings
424 which connects to a circuit that combines the outputs to produce a net energy
output. Other means and methods to connect the input and output power source
can also be used.
5
The power-generating magnets 416 are arranged in a circular form about the
central rotor shaft 414 such that upon rotation of the rotor shaft 414, the windings
424 also rotate about the central rotor shaft 414. In one embodiment, the rotation
of the windings 424 takes place in a clock-wise direction. In the alternative
10 embodiment, the rotation of the windings 424 takes place in an anti-clock-wise
direction. The rotation creates magnetic flux created by the magnets 416 and
windings 424 which results in enhancing the output power by at least two to three
times the input of power for example the input of 12 volts is converted into output
of 36 volts. The magnetic flux can be increased by increasing the rotation of the
15 rotor shaft 414. More rotation of the rotor shaft 414 will generate more power, for
example the input of 12 volts may be converted into output of 36 or 48 volts or
more depending on the rotation speed of the rotor shaft 414. The generated
electric power may be routed to a grid system or storage system for further use.
20 The number/quantity of magnets 416 shown in Fig. 10 is merely exemplary, and
the number of magnets 416 may be any number represented by 2n where ‘n’ is a
positive integer.
Yet another embodiment of the energy generating device of the invention is
25 shown in Fig. 11 and generally indicated with reference numeral 510. The energy
generating device 510 comprises a casing 512 and a rotor shaft 514 which is
arranged therein in a rotatable manner. A set of plurality of magnets 516R are
secured with equal spacing in an inner peripheral surface 538 of the casing 512 in
one side 559 thereof i.e. in the right side of the casing 512. The magnets 516R
30 are arranged around the rotor shaft 514 in circumferential direction/manner. In this
embodiment, eighteen magnets 516R as shown in Fig. 15 are secured on the
casing 512 with equal spacing such that N poles and S poles are alternately
arranged. Un-equal spacings between the magnets 516R can also be made in
alternative embodiments. The present embodiment is not limited to such a
25
structure, and another layer of magnets 516R as illustrated in Fig. 17 can also be
used. The first layer of magnets 516R is attached to the stator 572 and the second
layer of magnets 516R are attached to the inner wall of the casing 512.
A stator 572 is secured around in one side 559 of the rotor shaft 5 514 in a manner
to allow synchronous rotation. The stator 572 used in the invention is ring shaped
and has teeth which are formed in protruding manner and a plurality of windings
524R are wound around the teeth. However, the present invention embodies
stators of different shapes as well. Another set of plurality of magnets 516R are
10 also secured in-between the windings 524R as shown in Fig. 15. In this
embodiment, eight windings 524R and eight magnets 516R as shown in Fig. 15
are secured on the stator 572 which are alternately arranged. The length and
dimension of the set of plurality of magnets 516R used in this embodiment are
equal. Likewise, the length and dimension of the set of plurality of windings 524R
15 are equal. However, the length and dimension of the magnets 516R and windings
524R may vary in alternative embodiments.
The number of magnets 516R and windings 524R shown in this embodiment is
merely exemplary and may alternatively be any number represented by 2n where
20 ‘n’ is a positive integer. The stator 572 is arranged between third 548 and fourth
550 bearings.
Another stator 574 is secured around the rotor shaft 514 in a manner to allow
synchronous rotation in other side 560 of the casing 512 i.e. in the left side of the
25 casing 512. The stator 574 has an inner core 578 constituting plurality of windings
524L which include a three-phase winding (three phase winding refers to the
three wire Alternating Current (AC) power circuits i. e. (A, Phase B, Phase C)
power wires which are 120 degrees out of phase with one another) and one
neutral wire wound into the slots as shown in Fig. 14. In the alternative
30 embodiments, dual windings (a winding consisting of two separate parts which
can be connected in series or parallel. Also referred to as dual voltage or seriesmultiple
winding) may be used in dual voltage output designs, if desired or other
windings can also be used. A set of plurality of magnets 516L are secured on the
26
stator 574 over the inner core. The stator 574 being secured to the rotor shaft 514
is within a housing 570. A plurality of windings 524L are provided on the inner
surface 576 of the housing 570. The housing 570 is rotatably connected to the
rotor shaft 514. Since the housing 570 is integrally made with the rotor shaft 514,
the rotation of rotor shaft 514 causes the housing 570 to rotate 5 around stator 574.
Even when the rotor shaft 514 is rotated in the high-rotational speed which
generates heat, the possibility of the energy generating device 510 getting
damaged or its lifetime being shortened is reduced due to the rotor shaft 514
being provided with the housing 570. As well as the need of carbon brush and
10 sliprings for connection is also removed due to the provision of housing 570.
The device 510 is connected to a pair of input wires 542 which in turn is
connected to an external input power source, which may include solar, wind,
water or any other power source which drives the rotor shaft 514. The input power
15 source can also be Direct Current (DC) or Alternating Current (AC). The device
510 is further connected to output wires 558. The pair of input wires 542 usually
connect the windings (524R) to an external input power source; the pair of output
wires 558 usually connects the windings 524L to a circuit that combines the
winding outputs to produce a net energy output. Input 542 and output 558 wires
20 can be connected to the device 510 by known means.
The stators 572, 574 are a circular cylindrical structure co-axial with the rotor shaft
514 and is formed by stamping thin-plate for example, electromagnetic still plates
with a stamping die, layering a pre-determined number of stamped
25 electromagnetic steel plates and combining the plurality of layered such plates
through a known process.
In this embodiment, three windings 524L and ten magnets 516L as shown in Fig.
14 are secured on the stator 574. The length and dimension of the set of plurality
30 of magnets 516L used in this embodiment are equal. Likewise, the length and
dimension of the set of windings 524L used in this embodiment are equal.
However, the length and dimension of the magnets 516L and windings 524L may
vary in alternative embodiments.
27
The number of magnets 516L and windings 524L shown in this embodiment is
merely exemplary and may alternatively be any number represented by 2n where
‘n’ is a positive integer. The stator 574 is arranged between first 544 and second
556 bearings. The rotor shaft 514 is mounted on the casing 512 5 through the holes
of the four bearings 544, 546, 548, 550 and onto the coupling holes centrally
formed on the inner sides of the two covers 534, 536 of the casing 512.
The magnets securely attached to the inner wall 538 of the casing 512 can be
10 securely attached to the casing 512 as part of an integrated manufacturing
process of the casing 512. The magnets can also be welded, soldered, bonded or
glued or secured to the inner wall 538 of the casing 512 by any combination of two
or more such joining methods or permanently fixed/attached by other known
means, methods or materials.
15
The embodiments shown in Fig. 12 is similar to the embodiment shown in Fig. 11
except that the device 510 has only three bearings 544, 546, 548. As such, the
space in between the stator 572 and stator 574 is reduced.
20 Likewise, the embodiments shown in Fig. 13 is similar to the embodiment shown
in Fig. 11 except that the device 510 has only two bearings 544, 546, 548. As
such, the space in between the stator 572 and stator 574 is further reduced.
The phases of the stator windings 524R, 524L in the present embodiment include
25 3-phase AC output system but can be arbitrarily set by merely changing the
connecting methods of the output terminals and based thereon the degree of
freedom of design of the stators can be improved.
In the energy generating device 510 having such a structure, a voltage is induced
30 in the stator windings 524R, 524L by electromagnetic induction action caused
between a rotational magnetic field generated by a rotation of the rotor shaft 514
and stator windings 524R, 524L within the magnets 516R, 516L causing a current
to flow and power to be generated. The windings (524R, 524L) include a three28
phase winding or a dual winding or a combination thereof. While the magnet
portions are provided on the fixed portion of the casing 512 and the windings are
provided on the movable portion to constitute the electromagnetic induction type
power generating portion in the aforementioned embodiment, the present
invention is not restricted to this, but the magnet portions and 5 the windings may
alternatively be provided on the movable portion and the fixed portion
respectively.
The planning of magnets and windings used can be changed as shown in Fig. 16
10 which further illustrates an alternative embodiment of the invention. The stator 574
secured on the rotor shaft 514 may constitute only magnets 516L and a
combination of plurality of magnets 516L and windings 524L can be secured on
the inner surface of the casing 512 around the stator 574.
15 An advantage of this embodiment and other embodiments of the present invention
is in the provision of high efficiency energy generating device which can achieve a
high output with a simple structure and which can achieve size reduction and
reduction in the amount of materials used as well.
20 Referring now to FIG. 18, illustrated is a flow diagram of one of the preferred
embodiments of a method of constructing an energy generating device according
to the principles of the present invention. The method commences at a start step
110. The bearings, i.e. first, second, third and fourth bearings are secured on the
rotor shaft at step 112. Thereafter, a first winding is wound around a stator
25 provided in between first and second bearings and a second winding is wound
around another stator provided in between third and fourth bearings at the winding
step 114. A plurality of magnets are secured in the inner wall of the casing at step
116. The magnets used are, preferably unipolar magnets. Alternatively, bipolar
magnets can also be used. In some embodiments, one or more magnets are also
30 provided in between the said windings. In further alternative embodiments, one or
more windings are provided/secured on the inner wall of the casing. Various
combination of magnets and windings are possible on the inner wall of the casing
and on the rotor shaft. In one of the preferred embodiments, the length and
29
dimension of the magnets used are equal. The magnets and/or windings can be
secured by welding, soldering, bonding or glued or screwed or secured to the
inner wall of the casing by any combination of two or more such joining methods
or permanently fixed/attached by other known means, methods or materials.
Thereafter, the rotor shaft with the windings is inserted in the 5 casing at step 118
and input and output connections are secured on both sides of the rotor at step
120. In one of the embodiments, the input and output connections are secured
using carbon brushes connected to the winding of the shaft. The two side
openings of the casing are sealed by two side covers at step 122. The side covers
10 have outlets for input and output connections. The input and output wires are
connected to the winding of rotor shaft through a pair of carbon brush and
sliprings at both ends of the rotor shaft. The rotor shaft is arranged substantially in
center of the casing by movably securing the rotor shaft in the coupling holes
centrally formed on the sides of the two covers. The method of constructing an
15 energy generating device is completed at end step 124.
The invention has a large number of applications and can be used by solar power
plant producers effectively increasing the efficiency of the power plant at least by
two to three times. Likewise, the invention can be used by domestic households,
20 retail and commercial establishments which has the potential to reduce their
electricity/power loads and costs significantly.
The windings of the invention may consist clock-wise or anti-clockwise winding
when viewed along an axis of the coil. Alternatively, the windings of the invention
25 may also consist of a core-less or air core double winding structure in which the
coil includes at least one first clockwise winding and at least one second
counterclockwise winding when viewed along an axis of the coil in a multi-layered
stacked arrangement to generate maximum energy. The inner sides of either of
the plurality of windings (counterclockwise coil portions) or the plurality of windings
30 (clockwise coil portions) and the outer sides of either the plurality of windings
(clockwise coil portions) or the plurality of windings (counterclockwise coil
portions) are so connected or arranged with each other that the induced
electromotive force generated in said windings is not canceled. Thus, high
30
induced electromotive force can be obtained to efficiently generated maximum
energy. One of ordinary skill in the art will appreciate, however, that the specific
number of turns and wire type and size can be adjusted to satisfy specific
applications for energy generating device.
5
One or more sensors can also be used to manage the heat/temperature of the
energy generating device. The sensors can be arranged within the device. The
sensors are adapted to control the operation of the device once it nears a pre-set
temperature value in that once the device attain a set temperature it stops
10 operation.
The casing is made of a non-conducting and/or conducting, non-magnetic and/or
magnetic material such as plastic, aluminum, stainless steel, metal, glass etc. The
casing of the device is configured as such that it is sealed against the atmosphere
15 and completely leak proof, which isolates the internal components of energy
generating device from the environment, for example to render energy generating
device waterproof. It is also contemplated that the casing of the device maintains
a desirable environment, such as an inert gaseous environment or an
environment above atmospheric pressure or undesirable pressure crated due to
20 heat, motion, friction or temperature, which may increase and/or harm the
reliability and/or performance of the energy generating device.
The magnets used in the embodiments disclosed above are preferably permanent
magnets. While the permanent magnet is constituted as a multipolar magnet in
25 each of the aforementioned embodiments, the present invention is not restricted
to this but the permanent magnet may alternatively be constituted of a plurality of
bipolar magnets. Likewise, the present invention is not restricted to the use of
permanent magnet but an electromagnet may alternatively be employed in place
of the permanent magnet. The number of the permanent magnets used in the
30 afore-mentioned embodiments is merely exemplary, and may alternatively be any
number represented by 2n where n is a positive integer.
Those skilled in the art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and spirit of the
31
invention. For example, structural shapes of magnets of the invention are not
limited to those of the above embodiments as depicted in drawings, but rather
may include triangular, elliptical, or other geometric shapes. Further, the
arrangement of magnet structures is also not limited to unipolar magnets, but
rather can extend N-S polarities combination and to other combinations 5 of N-S
alternating polarities for example, N-S-N-S and/or N-S-S-N and/or S-N-N-S
polarity. Further, there is no limitation on the number of magnets and windings
which can be used for power generation following the above-discussed principles
and mechanism of the present invention. Likewise, there is no limitation on the
10 output of the energy being generated. The output of the energy can be increased
to from three, four, five, six times to ‘1n’ number of times, where ‘n’ is a positive
integer. Thus, it is intended that the scope of the present invention herein
disclosed should not be limited by particular disclosed embodiments described
above but should be determined only by a fair reading of the appended claims.
15

energy generating device and associated methods and of the manner
and process of making and using it in such full, clear, concise and exact terms as
