ABSTRACT:
The voltage that occurs across the run capacitor of a permanently split capacitor type motor when the motor is in operation is quite high compared to the voltage that is present if the motor is stalled. These different voltage conditions are sensed through the use of a voltage pickoff to control an optical type isolation circuit which in turn controls a switch means to energize a fault indicator.
