Abstract : The patent describes a direct current powered commutation and damping system for a servo motor having both forward and reverse direction commutation circuits that use silicon controlled rectifiers for control. A logic circuit with a plurality of sequentially timed outputs is used for controlling the period of the duty and the damping cycles. The damping cycle is on for about 5 percent of the entire system repetition period, and is specifically on during the off period of the motor power pulse.
