Abstract

PURPOSE: To widely control the rotational frequency of a motor by reducing the time constant of a control signal at frequency to voltage converting time lower than that of a signal from a frequency generator at frequency to voltage converting time and setting the time constant of a comparator at a value passing a low frequency signal.
CONSTITUTION: A control signal having a frequency proportional to desired rotational frequency is supplied through monostable multivibrators 2, 3 and an integrating circuit 4 to a comparator circuit 9. On the other hand, a signal from a frequency generator 6 is supplied through a monostable multivibrator 7 and an integrating circuit 8 to the circuit 9. The circuit 9 thus applies an error signal to a motor 5. The time constant of the integrating circuit 4 is reduced lower than that of the integrating circuit 8, and the time constant of the comparator circuit 9 is set at a value passing a low frequency pulse signal. Thus, the frequency can be controlled at low speed rotating time, and the voltage can be controlled at high speed rotating time.
