摘要： A stator includes a stator core, first to third phase windings, and a busbar unit. Each of the first to third phase windings includes segment conductors inserted into slots of the stator core, and has a power point and a neutral point each protruding from an end face of the stator core. The busbar unit includes first to third power busbars coupled respectively to the power points of the first to third phase windings, and a neutral busbar coupled to the neutral points of the first to third phase windings. In circumferential directions of the stator core, the neutral point of the third phase winding is disposed between the power points of the first and second phase windings, and the power point of the third phase winding is disposed between the neutral points of the first and second phase windings.

摘要： A stator for a rotary electric machine includes a stator core, a stator winding, a power bus bar, and a neutral bus bar. The stator core includes slots. The stator winding includes segment conductors inserted in the slots. The stator winding includes a power point and a neutral point. The power bus bar includes a bus bar end portion welded to a joint end portion of the segment conductor constituting the power point. The neutral bus bar includes a bus bar end portion welded to a joint end portion of the segment conductor constituting the neutral point. One or each of the respective bus bar end portions of the power bus bar and the neutral bus bar is located on an inner side of the joint end portion of the segment conductor to which the one or each of the bus bar end portions is welded.
