Abstract: A stator includes a stator core, a plurality of phase windings, a neutral line and a fixing portion. The plurality of phase windings is wounded a plurality of times by a predetermined winding method crossing between a plurality of slots. One lead end of each phase winding is a neutral point connecting portion, and the one lead end is pulled out from an axially end portion of the stator core. The neutral line connects the neutral point connecting portions of the phase windings of different phases together. The neutral line is separate from the phase windings. The fixing portion fixes a first phase winding that is connected to the neutral line. A second phase winding is adjacent to the first phase winding together.

Abstract: In a rotating electric machine, an armature winding includes segmented conductors that include a coil side portion, housed in slots of the armature, and a coil end portion protruding from an armature core on both sides in an axial direction. The coil side portions are housed in the slots so as to form 2N+1 layers in a radial direction. The coil end portion connects two coil side portions respectively housed in the slots that are a predetermined pitch apart in a circumferential direction. The coil end portion includes a first coil end portion connecting the coil side portions of differing layers in the radial direction and a second coil end portion connecting the coil side portions of the same layer. On both ends in the axial direction, any of the plurality of coil side portions that are housed in the slots is connected to the second coil end portion.
