Abstract

PURPOSE:To control the speed of an induction motor in stable and rapid response over a wide range by correcting the frequency command signal to suppress the variation in the magnetic flux upon change of a load of the motor. CONSTITUTION:The actual voltage value detected by a voltage detector 17 is compared with a voltage command value of a voltage instruction circuit 18, the deviation signal amplified by a voltage deviation amplifier 19 is added to the speed signal of a speed detector 5 and applied to a frequency command amplifier 20. The amplifier 20 applies a primary frequency command obtained by adding the rotating frequency and the slip frequency signal in response to the voltage deviation applied from the amplifier 19 to a voltage/frequency converter 13, thereby controlling the output frequency of a power inverter 3.
