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 has, at a portion facing the stator, different radial dimensions with respect to a rotary shaft of the rotor between a one end of the rotor in an extending direction of the rotary shaft and a portion different from the one end in the extending direction.
