A programmed power supply rectifies multi-phase A.C. power to produce signal polarity D.C. voltage and applies the D.C. voltage to the stator windings of a multi-phase motor in a predetermined sequence so as to develop a rotating magnetic field, and the motor responds thereto by rotating discrete mechanical increments in a step-by-step fashion. The stator windings are arranged in a star configuration having a neutral and each winding is energizable independently of the others. The power supply includes a triggerable rectifying element for each winding and a programmer which is responsive to an external source of signals for triggering the rectifying elements in the predetermined sequence.
