ABSTRACT:
This disclosure deals with single phase AC electric motors. The motor includes run and start windings, a start winding cutout switch connected in series with the start winding, and an electrical connector. Different power supply arrangements are provided which couple with the connector. One arrangement includes a power supply cable which supplies power and a jumper attachment which connects the start and run windings in parallel, thus causing the motor to operate as a split phase motor. In another arrangement, a cable supplies power and a capacitor attachment is provided for connecting the start winding to a start capacitor, thus causing the motor to operate as a capacitor start motor. The motor may be constructed to receive the attachments at either end of the motor.
