ABSTRACT:
A motor controlling system in which a stepping motor can be always stopped at a constant or predetermined position. During initialization an excitation phase is stored after the motor has been detected to have passed a particular position. During actual operation, after the motor has been detected to have passed that particular position, the excitation phase of the motor is monitored and compared with the stored excitation phase. The motor is stopped upon coincidence of the compared excitation phases.
