ABSTRACT:
An electric motor arrangement in which a modified induction motor is operated as a three-phase motor by connecting one of the input phases to the junction of the two motor windings, and by connecting the other two input phases to the other sides of the two motor windings. In one embodiment of the invention, one of the input phases is connected to the junction of the windings through a centrifugal switch. The induction motor may be a modified version of a permanent-split-capacitor type wherein the motor capacitor, conventionally connected across the free ends of the windings, is removed.
