ABSTRACT:
A motor speed regulating circuit includes a speed signal generator for generating a speed signal having a frequency proportional to the speed of the motor, synchronously with the rotation of the motor. A time difference detector is used for detecting a time difference between the period of the speed signal and a predetermined standard time. A control voltage generator is used for generating a speed control voltage to be applied to the motor in accordance with a detected time difference and feedback-controlling the speed of the motor in accordance with the standard time. A starter is used for starting the motor after the motor is stopped. The motor can be reliably restarted after it has been stopped.
