PROBLEM TO BE SOLVED: To provide a motor drive circuit capable of continuing three-phase drive of a motor by a rated output even when a drive system is damaged.SOLUTION: The motor drive circuit includes: a plurality of a drive circuits supplying an electric current from a power supply to a three-phase brushless motor; a power supply switch controlling connection of each of the drive circuits with the power supply; and at least two switching elements provided correspondingly to a coil of each phase of the three-phase brushless motor. Each of the two switching elements controls connection with any different one of the drive circuits.

    【課題】駆動系統が故障した場合であっても、定格出力によりモータの3相駆動を継続させるモータ駆動回路を提供すること。【解決手段】電源から3相ブラシレスモータへと電流を供給する複数の駆動回路と、各駆動回路と前記電源との接続を制御する電源スイッチと、前記3相ブラシレスモータの各相コイルに対応して設けられる少なくとも2つのスイッチング素子と、を有し、前記2つのスイッチング素子は、それぞれが、異なる駆動回路との接続を制御する、モータ駆動回路。【選択図】図1
