More Information
Summary: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 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.
