Abstract

PURPOSE:To stably operate a motor by providing a correcting circuit which produces a deviation when a voltage reference signal becomes larger than a voltage detection signal and decreasing the speed reference signal to the voltage detection signal by the correcting output at the stalling time of the motor. CONSTITUTION:A converter 2 controls a current depending upon signals from an oblique signal generator 8, a current sensor 13 and a voltage sensor 10, and an inverter 5 is controlled in its frequency by the output of a frequency generator 15 depending upon the voltage reference signal from the generator 8, thereby driving a motor 6. To a speed reference correcting circuit 31 are inputted a voltage detection signal VS and a voltage reference signal VREF, the circuit 31 operates as an integrator only when VREF>VS to produce an output DELTAv, which is inputted to the generator 8. When the motor 6 is accordingly stalled (VREF>VS), the generator 8 decreases the speed reference to the voltage signal VS and outputs it.
