PROBLEM TO BE SOLVED: To provide a motor capable of making small-sized a bus bar structure for supplying power to a plurality of coil groups divided into at least two coil groups of a first coil group and a second coil group on a three-phase basis and exciting a stator core with a three-phase AC, an electrically-driven power steering device and a vehicle.SOLUTION: The bus bar structure includes: a neutral point layer in which a plurality of neutral point conductors to be neutral points of coil groups are arranged in the same layer while being insulated, and a plurality of connection layers in which connection conductors in a three-phase input basis are arranged separately in a plurality of layers different from the neutral point layer while being insulated. The connection conductors of the same phase for each system arranged in the same layer are arranged at positions which are different in a planar view, while being insulated, and insulated from the connection conductors of different layers in an axial direction.
【課題】3相毎に少なくとも2系統の第1コイルグループ及び第2コイルグループとに分けられ、かつステータコアを3相交流で励磁する複数のコイルグループに電力を供給するバスバー構造体を小型にできる電動機、電動パワーステアリング装置および車両を提供すること。【解決手段】バスバー構造体は、各コイルグループの中性点となる複数の中性点導電体を同一層に絶縁配置した中性点層と、3相入力毎の各結線導体が、中性点層と異なる複数層に分けて絶縁配置された、複数の結線層とを有し、同一層に配置される各系統毎の同相の結線導体は、平面視で異なる位置に配置されて絶縁されるとともに、異層の結線導体と軸方向に絶縁される。【選択図】図9
