Abstract:
A rotary electric machine includes: a stator; and a rotor that face the stator and that rotates together with a rotation shaft, the rotor including: a rotor core including rotor salient poles and a slot formed between adjacent rotor salient poles, and a rotor coil wound around each of the rotor salient poles via an insulating member through the slot. Further, the rotor coil includes: a slot coil portion; and a coil end portion protruding from an end surface of the rotor core in an axial direction, the insulating member includes: a slot insulating portion; and an end insulating portion, and the slot insulating portion and the end insulating portion are integrated.
