ABSTRACT:
A control system for an induction electric motor utilized to drive a top loading agitator washing machine obviates the need for a mechanical transmission between the motor and the agitator of the washing machine. An integrated circuit module in the control system provides a nearly infinitely adjustable rate of output reversal. A plurality of phase shift capacitors enable a variety of output torques to be obtained from the motor.
