ABSTRACT:
A control system for a stepping motor in which a current (or voltage) to be fed to each excitation coil of the motor at the timing for an m-phase excitation is different from a current (or voltage) to be fed at the timing for an n-phase excitation. This difference in current (or voltage) causes a same torque to develop both in the m-phase excitation and n-phase excitation.
