ABSTRACT:
A motor includes a main frame with a stator unit and a rotor unit mounted within the frame. The frame extends axially from one end of the stator unit to form a compartment having an outer cylindrical wall. Power control components within the compartment are interconnected to each other and to the motor windings and incoming power and control cables within the compartment. An end cap closes the compartment. The cap includes a central opening. A door is releasably secured within the opening, with an electronic control module having heat sensitive elements secured to the inner wall of the door. The door is of cast aluminum having an inner mounting plate overlapping the opening and an integral decorative plate extended through the opening. The outer face of the decorative plate is recessed to define a logo or the like and increase the heat dissipation surface. The door and module have abutting inner planar surfaces for transfer of heat from the sensitive elements through the door to the surrounding environment. A second embodiment forms the compartment by a cup-shaped cover having a diameter of the main frame and secured extending axially therefrom. The access door is mounted in an end opening.
