ABSTRACT:
A system for controlling the operation of a polyphase DC motor having a rotor and a plurality of phase windings with separate outer terminals and a common center tap terminal supplies electrical energy sequentially to the phase windings to produce rotation of the rotor relative to the phase windings. The voltage between the outer terminal of one of the phase windings and the center tap terminal is sensed during periods when that one phase winding is not energized to control the sequential supplying of electrical energy to the phase windings.
