Abstract
PURPOSE: To suppress the turning speed of a motor to a slight deviation from a fixed speed even if the motor would be increasing in turning speed for phase correction after a torque disturbance dissappears, by exercising control so that the output a phase of a comparator will be decreased by the output of a detector.
CONSTITUTION: Motor 1, supplied with the voltage of reference voltage source 2 via driving circuit 3, turns and its turning speed is detected by detector 4 and converted 5 into a voltage signal, which is negatively fed back to the input side of circuit 3. The output of this converter 5 is input to attenuator 9 via detector 8 together with the output of phase comparator 6. As a result, the output signal of comparator 6 is decreased by the output of circuit 8 and even if the motor would be increasing in speed for phase correction after a torque disturbance disappears, the speed of the motor only changes slightly from a fixed speed.
