Abstract
A rotating electric machine includes a non-rotating member, a stator fixed to the non-rotating member, a field coil fixed to the non-rotating member, disposed on an inner diameter side of the stator, and having an iron core and a winding wound around the iron core, and a rotor rotatably disposed between the stator and the field coil. The rotor includes a first rotor portion and a second rotor portion. The rotating electric machine further comprises a positioning member disposed in each of the first gap, the second gap, and the third gap to position each of the first rotor portion and the second rotor portion in the circumferential direction and the extending direction.
