PROBLEM TO BE SOLVED: To provide a motor drive device which can improve energy efficiency of an electric automobile and a hybrid vehicle which travel by using a plurality of motors as power sources.SOLUTION: A motor drive device includes: first and second motors 3a, 3b which are connected so as to output power to a common output shaft 6 of a vehicle A; a first inverter device 2a which receives power through a junction box 2J and supplies power to the first motor 3a; a second inverter device 2b which receives power through the junction box 2J and supplies power to the second motor 3b; and a control device 10 which controls the first and second inverter devices 2a, 2b. The control device 10 operates the first and second motors by a torque distribution ratio determined by considering power loss in a power line from the junction box 2J to the first and second inverter devices 2a, 2b.SELECTED DRAWING: Figure 1

    【課題】複数のモータを動力源として走行する電気自動車やハイブリッド車輌において、エネルギー効率をより向上させることを可能とするモータ駆動装置を提供すること。【解決手段】車輌Aの共通の出力軸6へ動力を出力可能に接続された第1及び第2のモータ3a、3bと、ジャンクションボックス2Jを介して受電し、前記第1モータ3aに電力供給する第1のインバータ装置2aと、前記ジャンクションボックス2Jを介して受電し、前記第2モータ3bに電力供給する第2のインバータ装置2bと、前記第1及び第2のインバータ装置2a、2bを制御する制御装置10と、を備え、前記制御装置10は、前記ジャンクションボックス2Jから前記第1及び第2のインバータ装置2a、2bへ至るまでの電力ラインにおける電力損失を考慮して決定されたトルク分配比にて前記第1及び第2のモータを動作させる、モータ駆動装置。【選択図】図1
