ABSTRACT:
A two compartment motor has a frame, a pair of end shields disposed adjacent opposing ends of the frame to define a first compartment, a stator winding supported by the frame within the first compartment, an armature rotatably supported by the end shields and disposed within the first compartment adjacent the stator winding, a cover mounted to the motor adjacent one of the end shields to define a second compartment between the cover and the end shield, and a control plate mounted within the second compartment. The control plate serves as a mounting surface for securing a plurality of electrical components used in the control and operation of the motor in position within the second compartment. The control plate is a molded plastic component having integrally formed mounting mechanisms for at least one of the electrical components. The electrical components may include a starting capacitor, voltage and/or speed control switches, an overload device and electrical terminals. Ventilation openings, lead openings and shields may also be integrally formed in the control plate. The plate may be provided with recesses to accommodate electrical connectors, a centrifugal switch and other components. A method of assembling the motor includes mounting the plurality of components to the control plate to form a sub-assembly prior to connecting this sub-assembly to the other components of the motor.
