ABSTRACT:
An electric motor of a sewing machine may be stopped naturally at an objective position by amending the amount of the motor's running errors as overrun or underrun with respect to the stop objective position without employing an especially forceful stopping circuit in spite of dispersions in a load inertia caused by mass-production of sewing machines or variances in loads during driving of the sewing machine.
