PROBLEM TO BE SOLVED: To provide a motor controller capable of executing recovery processing of a failure in a motor controller and improvement in its reliability.SOLUTION: A motor controller 300 includes a plurality of control circuits 10, 20 and a plurality of motor circuits 100, 110. The motor circuit is constituted of an inverter circuit and a coil. The plurality of motor circuits are controlled by any one of control circuits or shared by the plurality of control circuits for control. When a failure occurs in any of the control circuits controlling the motor circuits under this condition, the control circuit is separated to make any other normal control circuit control the corresponding motor circuit for switching control. By executing these failure detection and switching control, the failure in the motor controller is recovered for high reliability.SELECTED DRAWING: Figure 2
【課題】モータ制御装置の異常の回復処理と、信頼性の向上をおこなう。【解決手段】モータ制御装置300は、複数の制御回路10,20と複数のモータ回路100,110とを有する。モータ回路は、インバータ回路とコイルとにより構成される。複数のモータ回路は、何れか一つの制御回路により、または複数の制御回路により分担して、制御される。この状態で、モータ回路を制御している何れかの制御回路に異常が生じた場合、この制御回路を切り離し、他の正常な制御回路に、対応するモータ回路の制御を行わせるように、切替制御を行う。これらの異常検出、切替制御は円滑かつ迅速に行なうことで、モータ制御装置の異常は回復処理され、信頼性が向上する。【選択図】図2
