PROBLEM TO BE SOLVED: To provide a motor controller capable of improving the output and reducing the torque ripple.SOLUTION: A motor controller 610 controls a driving current of a motor 200 having wirings 201 to 203 which are independently wound among the phases based on a torque command value T, an angular speed ω and rotator position θ of the motor 200. The ratio of zero-phase current in the driving current (i, i, i) is controlled to change depending on the torque command value T. As a result, the output is improved; and when the torque command value Tgets smaller, and the ratio of the zero-phase current in the driving current becomes smaller and the torque ripple is suppressed.SELECTED DRAWING: Figure 3

    【課題】出力の向上およびトルクリプルの低減を図ることができるモータ制御装置の提供。【解決手段】モータ制御装置610は、相間で独立して巻かれた巻線201〜203を有するモータ200の駆動電流を、トルク指令値T*とモータ200の角速度ωおよび回転子位置θとに基づいて制御する。そして、駆動電流(iu、iv、iw)における零相電流の比率をトルク指令値T*の大きさに応じて変化させる。その結果、出力の向上が図れると共に、トルク指令値T*が小さくなると駆動電流における零相電流の比率が小さくなりトルクリプルが抑制される。【選択図】図3
