Abstract

PURPOSE: To accomplish highly accurate speed regulation even under thermal disturbance by providing a pulse operation unit which generates a control signal; and a differential unit, which controls a supplied voltage, between a speed setting unit and a control unit.
CONSTITUTION: A control unit 6, which controls a voltage supplied from a speed- setting unit 5, is intervened between the speed setting unit 5 and a variable-speed motor unit 4, and pulses based on frequencies generated by a generator 3 is generated by a pulse generator 7. A pulse signal P8, which is generated in a voltage-frequency conversion unit 8 by digitally converting a voltage V5 or corresponding voltage V'5 supplied from the unit 5, and a pulse signal P7 from the pulse generator 7 are calculated in a pulse operation unit 9, thereby a control signal is generated. A differential unit 10 receives the control signal, and controls the voltage supplied by the speed-setting unit 5, thereby highly accurate speed control can be accomplished.
