A collectorless D.C. motor includes a rotor, a stator, and a plurality of stator windings arranged on the stator in angularly spaced relationship. Each winding when energized produces a stationary magnetic field having a respective orientation. A control circuit including an oscillator energizes successive ones of the windings for respective time intervals determined by the oscillatory frequency of the oscillator. The resulting magnetic field revolves with an angular velocity determined by the oscillator.
