    • The present invention provides an automotive rotary electric machine and a stator manufacturing method that is used therefor in which radial widths of return portions of winding assemblies that constitute coil ends of a stator winding that are stacked in a radial direction are made sequentially greater in an outer layer, an inner layer, and an intermediate layer to enable mounting into a stator core of winding assemblies that use wires that have large cross-sectional areas, to suppress bulges in a radial direction of coil end groups, and to enable interference with a housing and a rotor to be avoided.
      The stator winding has winding assemblies that are disposed in a stator core so as to be stacked in three or more layers in a radial direction such that slot-housed portions line up in single columns in a slot depth direction inside slots, and radial widths of return portions of the winding assemblies that are mounted so as to be stacked in a radial direction are made sequentially narrower in order of return portions of a winding assembly that is positioned centrally, return portions of a winding assembly that is positioned on an inner circumferential side, and return portions of a winding assembly that is positioned on an outer circumferential side.
    • 本发明提供车用旋转电机上,并且一个定子制造方法并为此使用在绕组组件的返回部分的哪一个径向宽度并构成一个定子绕组没有被堆叠在径向方向上的线圈端部由在外侧按顺序更大 层到内层,和在中间层,以使安装到绕组组件的定子铁心并使用电线thathave大的横截面面积,以抑制在线圈端组的径向方向上凸起,并能够与外壳干涉 和要避免的转子。 定子绕组具有绕组组件并在一个定子铁心设置成在三个或更多层在径向方向上的搜索没有槽收纳部在单个列在里面的槽的槽深度方向排列的堆叠,和径向宽度 该绕组组件的返回部分没有被安装,以在径向方向上被堆叠在一个绕组组件那样居中地定位的返回部分的顺序进行顺序地窄,返回一个绕组组件的部分没有被定位在帧内周侧 并返回一个绕组组件的部分没有被定位在到外周侧。
