FIELD OF THE INVENTION
The present invention generally relates to a apparatus for providing support to vertical TEFC (totally enclosed fin cooled) motor in horizontal condition. The vertical TEFC motor is required to be tested horizontally when coupled with Tandem for direct loading in order to obtain precise and accurate results which are normally difficult to achieve when vertical motors are tested in vertical condition by mixed frequency method.
BACKGROUND OF THE INVENTION
Construction of Vertical TEFC motor is such that it has fins around the motor body, except the four air channel pockets for internal air circulation. In absence of base and available fins around the motor body, it is difficult to place motor in horizontal condition on the test bed for coupling with load. In such situation, Vertical TEFC motor undergoes type testing by mixed frequency method. Unfortunately, this method evaluates temperature rise of machine but other important parameters like power factor, slip cannot be evaluated.
OBJECTS OF THE INVENTION
It is therefore an object of the invention, to propose a rigid testing stand of Vertical TEFC motor for horizontal testing by direct loading through tandem.

It is also an object of the invention to evaluate the motor parameters like power factor, slip etc. of vertical TEFC motor testing horizontally through tandem loading on testing stand.
SUMMARY OF THE INVENTION
According to the invention there is provided a rugged and safe, two point support testing stand for vertical TEFC motor testing in horizontal condition by direct loading through tandem. The two point supports are situated in DE (Drive end) and NDE (Non drive end) side. The finned construction of the motor frame body acts as a support from body challenging, as the damage of fins in terms of cooling and aesthetics aspect are not allowed. Thus, an assembled motor DE end shield which is of flange type is to be used for testing stand support. Since the outer periphery of flange is circular, the support of testing stand is semicircular matching to the outer periphery of flanged end shield, and slotted hole profile on stand is bolted to end shield., which also acts like a locating /fixed support for test stand. The non-drive end of motor contains fan casing and canopy which cannot take radial load of motor. Thus, motor at NDE end is to be supported by air pocket channel. Moreover, 90 degree apart air pocket channel supported by V-type configuration block of the testing stand provides trouble-free support and ruggerdness to the system.

DETAIL DESCRIPTION OF THE INVENTION
FIG-1 shows a conventional vertical TEFC motor outer details.The tangible outer detail consists of flange type DE (Drive End) end shield (B), motor body (A), fan casing (C), air pocket channel and canopy (D), and shaft extension (E). The vertical TEFC motor generally undergoes type testing by mixed frequency method.
FIG-2 shows a test stand (2A) which supports the vertical TEFC motor from drive end flanged end shield (fig. 1-B) when motor is in horizontal condition.
There is semi-circle profile of test stand matching to the drive end flange type end shield (fig. 1-B) profile, which rather gives support and rigidity by fixing with the existing hole in end shield.

FIG-3 show a test stand (2B) which supports the vertical TEFC motor from non-drive motor body (fig. 1-A) through air pocket channel (fig. 1-F) when motor is in horizontal condition.
The V- profile of test stand (2B) holds the 90 degree apart air pocket channel (fig. 1-F) of vertical TEFC motor body (fig. 1-A),
FIG-4 shows a schematic diagram of how vertical TEFC motor is to keep on the testing stand 2A and 2B for testing through tandem.
FIG-5 shows the 3D view of complete testing set up of vertical TEFC motor.
FIG-6 shows the pictorial view of how vertical TEFC motor is placed horizontally on testing stand and coupled with Tandem.
