ABSTRACT:
One coil of a bifilar winding of a stepping motor is energized until the current therein reaches a set value and then energization is terminated which creates an induced current that supports the magnetic flux produced by the energizing current and in which the duration of the induced current is increased by being directed through both coils of the winding thereby decreasing the motor's power requirements.
