Abstract
The bearing plate assembly is removably attached to an end housing of an electric motor in which the end housings of the motor are permanently affixed to the laminated body of the motor by means of anaerobic adhesive. The bearing plate assembly is attached to the end housing by the use of two short thread cutting screws so that it can be quickly and easily removed and replaced. When the bearing plate assembly is removed, the rotor of the motor may be extracted from the housing and reversed so as to reverse the direction of rotation of the motor. The bearing plate assembly is then replaced to complete the reassembly of the motor. By this construction, a motor can be made to run either in a clockwise or counterclockwise direction as desired.
