ABSTRACT:
A circuit which enables a three phase, Y connected motor to be operated on either one phase or three phase power at either 230 or 460 AC line voltage. A modified circuit includes power factor correction capacitor banks for increasing the power factor and efficiency of the motor whether connected for one phase or three phase operation at either line voltage.
