To provide a motor controller more accurately detecting a rotation angle of a rotation shaft.SOLUTION: A motor controller 100 comprises: a plurality of rotation position sensors 10 for detecting a rotation position of a rotation shaft of a motor MT; and a sensor setting unit 22 that evaluates a performance of the plurality of rotation position sensors by a predetermined evaluation method and, on the basis of the evaluation, sets a control rotation position sensor to be used for motor control out of the plurality of rotation position sensors. The sensor setting unit electrifies the motor in a plurality of drive modes in which the rotation shaft stops at predetermined reference positions and evaluates a performance of the rotation position sensors by the predetermined evaluation method using detection positions based on output of the rotation position sensors acquired in each drive mode and a reference position.SELECTED DRAWING: Figure 4

    【課題】回転軸の回転角の検出精度を向上させたモータ制御装置を提供する。【解決手段】モータ制御装置100は、モータMTの回転軸の回転位置を検出する複数の回転位置センサ10と、複数の回転位置センサの性能を所定の評価方法で評価し、その評価に基づき複数の回転位置センサの中からモータ制御に用いる制御用回転位置センサを設定するセンサ設定部22と、を備える。また、センサ設定部は、回転軸が所定の基準位置で停止する複数の駆動モードでモータに通電し、駆動モードごとに取得する、回転位置センサの出力に基づく検出位置と基準位置とを用いて所定の評価方法で前記回転位置センサの性能を評価する。【選択図】図4
