Abstract
A stator of a rotating electric machine includes a plurality of coil units. Each of the plurality of coil units includes a conductive wire bundling portion in which end parts of a plurality of conductive wires are bundled together and connected. The rotating electric machine includes a neutral point bus bar, and a plurality of conductive bus bars. When one end part in an axial direction of the rotating shaft is viewed from the axial direction, the neutral point bus bar, the plurality of conductive wire bundling portions, and the plurality of conductive bus bars are aligned in this order from inwardly toward outwardly in a radial direction of a rotating shaft.
Claims9
A rotating electric machine system comprising:
- a rotating electric machine comprising a rotor including a rotating shaft, a stator including a plurality of coil units, and a connector including a plurality of terminals configured to electrically connect the plurality of coil units to an external device;
- and
- a rotating electric machine housing on which the rotating shaft is rotatably supported;
- wherein the stator comprises a stator core;
- each of the plurality of coil units comprises a plurality of coil portions formed by winding a plurality of conductive wires respectively around the stator core, and a conductive wire bundling portion in which end parts of the plurality of conductive wires are bundled together and connected;
- the rotating electric machine comprises a neutral point bus bar configured to be electrically connected to neutral points of the plurality of coil units, and a plurality of conductive bus bars configured to electrically connect, respectively, the plurality of conductive wire bundling portions and the plurality of terminals;
- and
- the neutral point bus bar, the plurality of conductive wire bundling portions, and the plurality of conductive bus bars, when one end part in the axial direction of the rotating shaft is viewed from the axial direction, are aligned in this order from inwardly toward outwardly in the radial direction of the rotating shaft, and further, when the rotating shaft is viewed from a direction perpendicular to the axial direction, are aligned in this order in the axial direction from an intermediate portion of the rotating shaft in the axial direction toward the one end part.
