前記電動機駆動手段と前記ブラシレスモータとを接続する複数のラインのうち、任意の1本のラインを除く他の複数のラインに電流検出手段と自己のラインを開閉する開閉手段との双方が直列に挿入され、前記任意の1本のラインには、前記電流検出手段とインピーダンス値がほぼ等しいインピーダンス素子が挿入されていることを特徴とする電動パワーステアリング装置。 An electric motor driving means for driving a brushless motor that applies a steering force to the steering system by switching operations of a plurality of switching elements constituting the bridge circuit, wherein the electric motor driving means is based on a target current corresponding to the magnitude of the steering input. An electric power steering device for driving the brushless motor,
Of the plurality of lines connecting the electric motor driving means and the brushless motor, both the current detection means and the opening / closing means for opening and closing the own line are connected in series to a plurality of lines other than any one line. An electric power steering apparatus , wherein an impedance element having an impedance value substantially equal to that of the current detection means is inserted in the arbitrary one line .
