ABSTRACT:
A self-starting rotary converter for connection to a single-phase a.c. power source and for supplying polyphase current to a polyphase electrical load. A generally annular polyphase stator has a predetermined number of poles and at least three stator windings symmetrically oriented physically and electrically. An induction rotor positioned within the stator rotates about a central axis thereof when the stator is energized by single-phase a.c. power. One of the stator windings has at least one electrical tap positioned intermediate its ends, and a second stator winding has one of its ends connected to the tap to effect electrically nonsymmetrical operation of the stator. This maintains the currents supplied to the phases of the polyphase load at its maximum rating substantially balanced.
