ABSTRACT:
An improved control system for energizing a stepping motor varies the width of the stepping pulse to the stepping motor as the motor transfers from one balanced state to another in order to provide additional starting torque and disconnects the energizing source from the motor when the motor is in its balanced state in order to conserve energy.
