ABSTRACT:
Described herein is a phase locked servo loop circuit which causes a DC mr to operate synchronously regardless of DC motor load. The circuit comprises a pick-off device which generates an integral number of voltage pulses each time the motor rotates through 360.degree. and a clock pulse generator that provides fixed frequency pulses. The output pulse of the pick-off device is applied to the input of a logic circuit which either opens or closes a switch in response to phase differences between the train of pick off pulses and the train of clock pulses to control the speed of the motor.
