ABSTRACT:
The tendency of a unipolar energized stepping motor, having a circuit for enabling the self-decay of winding currents, to oscillate or flutter under some mid-velocity conditions is minimized by reducing the deviation of the motor's rotor from the synchronized position dictated by the energization of its winding by inversely altering the time about a nominal time when a change of the motor's energization is to occur after receipt of an input pulse in accordance with the extent of the decay current in the winding being deenergized.
