To provide a motor drive device capable of making a control system redundant, improving a noise resistance performance and effectively utilizing it to improve a control performance, and an electric vehicle with the motor drive device.SOLUTION: A motor drive device 6 comprises: a current drive circuit 8; a current sensor S for detecting a current flowing to a motor 4; and a control device 9 which gives a current driving signal to the current drive circuit 8 on the basis of a torque command and the current detected by the current sensor S. As the current sensor S, current sensors to be two pairs capable of detecting a magnitude and a direction of the current are provided in a mutually opposing direction and in any two phases in three phases. The control device 9 includes differential calculation means 16 which calculates a differential of currents detected by the paired current sensors for each of the two phases including the paired current sensors, cancels in-phase noise superimposed on output of the paired current sensors, and uses obtained current values to perform current control.SELECTED DRAWING: Figure 3

    【課題】制御系の冗長化を図ると共に、耐ノイズ性能を高め、制御性能の向上に活用することができるモータ駆動装置およびこのモータ駆動装置を備えた電気自動車を提供する。【解決手段】このモータ駆動装置6は、電流駆動回路8と、モータ4に流れる電流を検出する電流センサSと、トルク指令および電流センサSで検出された電流に基づいて電流駆動回路8に電流の駆動信号を与える制御装置9とを備える。電流センサSとして、電流の大きさと向きを検出可能な二個の対となる電流センサを、互いに対向する向きに、且つ、三相におけるいずれか二相にそれぞれ備える。制御装置9は、対の電流センサを備える二相における各相につき、対となる電流センサでそれぞれ検出された電流の差分をとって、対となる電流センサの出力に重畳された同相ノイズを相殺し、得られた電流値をそれぞれ用いて電流制御を行う差動演算手段16を有する。【選択図】図3
