ABSTRACT:
A motor controller system comprises solid state switches for connection between an AC line and motor terminals for controlling application of AC power to the motor. A user input elements selects a current imbalance parameter. Current sensors sense current in each winding of the motor. A control circuit controls operation of the solid state switches. The control circuit compares the sensed currents with the selected imbalance parameter to determine if a fault condition exists.
