ABSTRACT:
A control circuit for connection to a split capacitor motor automatically switches to reverse operation when the motor is caused to stop or slow unacceptably by a heavy load. During operation, a voltage is maintained across a relay winding which is sufficient to hold the relay contacts in the normally open position. A slowing or stopping of the motor causes a reduction the voltage across the relay winding, which permits the relay contacts to switch to a configuration that reverses the phase of the current through the main and auxiliary windings of the motor, thereby reversing the motor.
