Abstract: PURPOSE:To prevent a torque ripple from generating from an AC motor by compensating an output voltage drop due to the ON delay of an inverter. CONSTITUTION:A compensating voltage calculator 12 calculates voltage command signals  V'u,  V'v,  V'w for compensating an output voltage drop due to the ON delay of an inverter 2 on the basis of an exciting current command signal I'd, a torque current command signal I'q and a primary angle frequency command signal omega'1, and outputs it to an adder 13.
