Abstract: Disclosed is a circuit for regulating a d.c. motor that makes use of the inductive reactance of the motor and utilizes a switching regulator to regulate the current to the motor. This system has the advantage of allowing the transistors of the servo amplifier to be in either fully on or fully off condition thereby reducing the power dissipation within the amplifier.

Abstract: Disclosed is circuit means for controlling the torque of the servo motor with respect to the speed of the servo motor. This system finds particular application in document feed apparatus where it is useful to maintain constant torque over a range of speeds. The control circuit includes a speed sensing element, switching elements and a servo amplifier for applying power to the servo motor. This system may also be adapted to compensate for the damping constant of the servo motor.
