PROBLEM TO BE SOLVED: To provide a control device of an electric motor vehicle that has a function for preventing overheat burnout of an induction motor by detecting abnormality when a phase sequence of the induction motor driven by an inverter device of the electric motor vehicle is an erroneous interconnection, and by cutting off power supply to the induction motor, and for notifying a crew member of the electric motor vehicle of the erroneous interconnection of the induction motor.SOLUTION: A control device of an electric motor vehicle comprising a power converter for driving multiple induction motors detects erroneous interconnection of a phase sequence of at least one among the multiple induction motors on the basis of a fact that: a notch command from a control platform of the electric motor vehicle is a prescribed value or lower, and speed of the electric motor vehicle is equal to or higher than a first prescribed value and equal to or lower than a second prescribed value; and a torque current ACR operation amount, which is obtained from a difference between a torque current pattern acquired from the speed and the notch command and a torque current detection value acquired from a detection value of the electric motor current outputted from the power converter, is equal to or higher than a prescribed threshold value.SELECTED DRAWING: Figure 1

    【課題】電気車のインバータ装置で駆動される誘導電動機の相順を誤って配線した場合に、その異常を検知して誘導電動機への電力供給を遮断し誘導電動機の過熱焼損を防止すると共に、電気車の乗務員に対し誘導電動機の誤配線を通知する機能を有する電気車の制御装置を提供する。【解決手段】複数の誘導電動機を駆動する電力変換器を備えた電気車の制御装置において、電気車の運転台からのノッチ指令が所定値以下で該電気車の速度が第1の所定値以上及び第2の所定値以下であり、かつ、前記速度及び前記ノッチ指令から得られるトルク電流パタンと前記電力変換器から出力される電動機電流の検出値から得られるトルク電流検出値との差から求めるトルク電流ACR操作量が所定の閾値以上となることから、前記複数の誘導電動機の内少なくとも1台の相順が誤配線であることを検知する。【選択図】図1
