Abstract

PURPOSE: To provide a control operation with high efficiency of the integrated operation, by providing a correlation between an applied voltage and a load torque of the motor.
CONSTITUTION: The output of a voltage frequency converter 3 is being applied to a frequency voltage converter 8. Because an output of the frequency voltage converter 8 is made feed-back to a frequency command voltage 1, the period, getting longer by an increase of the load, that is, a lowered frequency is corrected to the frequency before an increase of the load torque by means of raising an output of DC variable voltage. And this results in an increase of only the voltage for an increase of the load, with few amount of change caused in the frequency, and an applied voltage of the motor will be made to be controlled by the load torque.
