PROBLEM TO BE SOLVED: To reduce the number of switching times when reducing a zero-phase current.SOLUTION: The motor controller, controlling a motor with respective phases independently connected, includes control means of outputting a PWM control signal for controlling a voltage applied to the motor on the basis of an input torque command. The control means controls a pulse width and an amplitude of a zero-phase voltage constituted of a sum total of output voltages on the basis of a zero-phase voltage command for suppressing a zero-phase current obtained from an alternating current of the motor.SELECTED DRAWING: Figure 5

    【課題】本発明の目的は、零相電流を減少させる際のスイッチング回数を低減することである。【解決手段】各相が独立して結線された電動機を制御する電動機の制御装置であって、入力されたトルク指令に基づき電動機へ印加する電圧を制御するためのPWM制御信号を出力する制御手段を有し、前記制御手段は前記電動機の交流電流から求められる零相電流を低減するための零相電圧指令に基づき、出力電圧の総和からなる零相電圧のパルス幅及び振幅を制御する。【選択図】 図5
