Abstract
A rotating electric machine includes a multi-phase coil, an armature core, a rotor, a yoke core and a superimposer. The armature core has the multi-phase coil wound thereon. The rotor is rotatably disposed and has a plurality of magnetic poles facing the armature core. The yoke core is arranged so as to surround outer peripheries of the multi-phase coil and the armature core. The yoke core is magnetically connected with the magnetic poles of the rotor. The superimposer superimposes a DC component on a multi-phase alternating current supplied to the multi-phase coil, thereby supplying a DC field magnetic flux to a magnetic circuit that is formed by the armature core, the magnetic poles of the rotor and the yoke core.
