ABSTRACT:
A motor control apparatus comprises the amplitude adjustment section and the peak voltage control section so as to adjust the torque control output in correspondence with the output voltage of the inverter. The peak voltage control section detects the peak voltage of the voltage command, and outputs the adjustment command instructing the amplitude adjustment section to suppress the amplitude when the peak voltage possibly exceed the previously determined value which is determined with respect to the maximum output voltage or maximum modulation rate of the inverter. The amplitude adjustment section lowers the gain by carrying out processing such that a constant proportional value is removed from the integration value, for example, in response to the supplying of the adjustment command.
