Abstract:
Provided is a rotating electric machine capable of downsizing a coil end. The rotating electric machine includes an armature core and a plurality of coils. The plurality of coils each include a plurality of turn portions. The plurality of turn portions each include an inner-layer-side turn portion and an outer-layer-side turn portion. The inner-layer-side turn portion includes a first inner-layer-side bent portion, a first inner-layer-side oblique portion, and an inner-layer-side shift portion which is twisted. The outer-layer-side turn portion includes a first outer-layer-side bent portion, a first outer-layer-side oblique portion, and an outer-layer-side shift portion. The outer-layer-side shift portion has the inner-layer-side shift portion arranged between the outer-layer-side shift portion and the armature core.
