PROBLEM TO BE SOLVED: To provide a motor control device in which torque ripple and so on are inhibited by providing a filter that offsets the electric characteristics of a motor having multi-system coils even if there are variations in hardware, and to provide an electric power steering device having improved feeling of steering.SOLUTION: In a motor control device including a control part that calculates a current command value 2 by carrying out distribution for each multi-system coil of a motor according to a current command value 1 and that controls the multi-system coils of the motor on the basis of the current command value 2, the characteristics of electric characteristic parts of the multi-system coils are offset, and a reverse characteristic filter for setting a required motor electric characteristic is provided for an operating path for the current command value 2 for each multi-system coil.SELECTED DRAWING: Figure 5

    【課題】ハードウェア上のバラツキがある場合でも、多系統巻線を有するモータの電気特性を相殺するフィルタを設けることで、所望のモータ電気特性が得られる電流指令値の生成が可能となり、トルクリップル等が抑制されたモータ制御装置及び操舵フィーリングを向上した電動パワーステアリング装置を提供する。【解決手段】電流指令値1に従いモータの多系統巻線毎に分配して電流指令値2を演算し、電流指令値2に基づいてモータの多系統巻線を制御する制御部を具備したモータ制御装置において、多系統巻線の各電気特性部の特性を相殺すると共に、多系統巻線毎に、所望モータ電気特性を設定する逆特性フィルタを電流指令値2の演算経路に設ける。【選択図】図5
