FIELD OF INVENTION
[001] The present invention generally relates to electric ceiling fans which are powered by rechargeable batteries. More specifically, it relates to the combination of small fans which rotates with the rotation of electric celling fan to make the ceiling fan to run on its own output when there is no electricity.
BACKGROUND OF THE INVENTION
[002] The energy can be transformed from one form to another. But we are wasting resources that can produce energy as if they are boundless. If we can renew and reuse the energy we untapped, it would help in some way to the problem of inadequacy of energy, which is the major threat to the fast moving world.
[003] Ceiling fans are one of the common electric appliances used in every home since electrical energy became available on an extensive basis to various locations at which humans are frequent, including but not limited to working places, homes, godowns, and any other closed infrastructures.
[004] Ceiling fans are presently used extensively to enhance personal comforts by providing airflow in areas where there is insufficient electric power or no electricity for the powering the highly sophisticated air conditioners especially in urban locations. Thus deriving power from various alternate sources such as solar panels are used for powering the ceiling fans.
[005] The existing prior arts where the ceiling fans run by the energy harvested from the solar panels are also having limitations of the areas where it is used such as cold countries where the solar energy is not sufficient enough for the generation of electric power.

[006] A United States patent US6095767A describes independent ceiling fans powered by rechargeable batteries. The fans do not require energy from hard-wired sources and they can be installed in any location preferred by the user. A battery is located at the centre at the axis of rotation of the fan blades, to converse the increased balance and constancy to the device.
[007] Another prior art, the United States patent US20150004022A1 describes a ceiling fan with a fan motor and blades are suspended from the ceiling using a mounting tube and a power supply attached along within the mounting tube is organized to power the motor of the fan. The Light-Emitting Diodes (LED) is fitted at the middle of the fan which stays stationary and the blades revolve around it. The user can control the fan operations which are implemented through an infrared remote control transmitter, with control signals received by infrared receiver mounted directly on motor controller. These types of ceiling fans consume more power with these additional fittings of light, etc.
[008] Therefore there exist a need to design an energy harvesting system which overcomes the above mentioned limitations and make the fan to run with some alternative source that doesn't rely on any natural or seasonal energy and make the fan to run when there is no electricity.
SUMMARY OF THE INVENTION
[009] The following summary is provided to facilitate a clear understanding of the new features in the disclosed embodiment and it is not intended to be a full, detailed description. A detailed description of all the aspects of the disclosed invention can be understood by reviewing the full specification, the drawing and the claims and the abstract, as a whole.
[010] It is therefore one aspect of the present invention is to run the electric ceiling fan which consumes less or zero electricity without rely on any natural or seasonal energy to reduce the energy consumption.

[011] The aforementioned aspects along with the objectives and the advantages can be achieved as described herein.
[012] The objective of the present invention is to design a fan mill, which can make the ceiling fan to run on its own output when there is no electricity.
[013] In another aspect of the present invention, a plurality of small fans fitted with motors and those motors fitted with batteries which can rotate with the rotation of the ceiling fan in such a way that the battery can store the charge produced by the rotation of that connected motors. Here the motor act as the generator which outputs the electric power by taking the mechanical rotation as input.
[014] When the electric ceiling fan rotate itself , the small fans assembled nearer to the fan can receives the wind delivered by the main ceiling fan and those small fans also start to rotate by that wind energy. As a result of the rotation of the plurality of small fans, the electricity produced and each battery of the small fans will store the electricity.
[015] The stored charge in all the small batteries gets transferred to the ceiling fan to make it run, when there is insufficient electric power or no electric power. The present invention fan mill saves the electrical energy and cost involved.
DETAILED DESCRIPTION:
[016] The following detailed description illustrates by way of example and not by way of limitations. Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings in which like numerals represent like elements throughout the several figures, and in which example embodiments are shown. Embodiments of the claims may, however, be embodied in many different

forms and should not be construed as limited to the embodiments set forth herein.
[017] In the disclosure herein, consideration or use of a particular element
number in a given FIGURE or corresponding descriptive material can
encompass the same, an equivalent, or an analogous element number
identified in another FIGURE or descriptive material corresponding
thereto. Some embodiments of this invention, illustrating all its features,
will now be discussed in detail. The words "comprising," "having,"
"containing," and "including," and other forms thereof, are intended to be
equivalent in meaning and be open ended in that an item or items
following any one of these words is not meant to be an exhaustive listing
of such item or items, or meant to be limited to only the listed item or
items. _
[018] It must also be noted that as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Although any systems and methods similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present invention, the preferred, systems and methods are now described.
[019] In the present invention, a plurality of small fans 102 with motor connected to the battery 103, are placed in the wind zone of the ceiling fan. When the ceiling fan 101 rotates, the battery connected to the motor of each small fan 103 can store the charge produced by the rotation of that connected motors.
[020] When the ceiling fan 101 starts rotating, the wind from the ceiling fan 101 is utilized by the plurality of small fan 102. When the wind strikes the blades of the small fans 102, a motor inside the fans starts rotating. The stator of the motor which is formed by loading an encoded number of metal plates is fixed on the motor hinge.

[021] The stator is surrounded with a plurality of first magnetizing coils, each of which is winded with a second magnetizing coil and it detects the received EMF around it. The stator has a static number of identically spaced coil arms in the vertical direction toward the motor hinge.
[022] The rotor with several permanent magnets around the stator is centrally mounted on the motor hinge through a bearing. The rotor is bounded with numerous connecting parts for fixing a blade frame with several blades. Each of the first magnetizing coils is driven by the input voltage to produce an induced magnetic field. The rotor is thus driven to rotate with respect to the stator and build up inertia. The rotor rotates with respect to the stator, and cuts through the magnetic lines.
[023] Then the back EMF is created in the induced magnetic field. The second magnetizing coil on the stator detects the received electromotive force which is then transformed into electrical power and then stored in the battery 103 fitted with the motor of the fan.
[024] Fig. 1 illustrates the experimental set-up of the Fan mill. A ceiling fan 101 electrically connected at the top of the roof and a plurality of small fans 102 with motor fitted and a battery 103 fitted with the motor of small fans 102. When the ceiling fan 101 rotates, the wind energy strikes the blades of the small fan 102.
[025] The small fan 102 rotates and the motor connected with the small fan 102 also rotates, the energy produced by the motor is stored in the battery 103 attached with the motor. The stored energy can be used to run the ceiling fan 101 when there is no electricity and saves the electrical energy.
