ABSTRACT:
A frame for the housing of an electric motor having a top cavity that extends axially along the upper interior portion of the frame and beneath the top wall of the frame. The top cavity functions as a conduit box through which access is provided to the electrical leads of the motor, thus eliminating the need for a separate conduit box attached to the exterior of the housing. The frame also includes an axially extending, corner channel along each of its four corners. The frame is adaptable for both closed and open housing cooling arrangements.
