Abstract

A rotating electric machine includes a stator core, a stator winding, and a rotor rotatably disposed via an air gap so as to be allowed to rotate relative to the stator core. A magnetic resistance-altering portion is provided on every other magnetic pole of magnetically-assisted salient pole members. A magnetic pole provided with the magnetic resistance-altering portion and a magnetic pole without the magnetic resistance-altering portion are alternately arranged.
