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.

Abstract: A double-stator electric rotating machine with a retainer. The retainer includes a connector which joints between an outer stator and an inner stator. The retainer is placed in contact with an outer peripheral surface of the outer stator and an inner peripheral surface of the inner stator to retain the outer and inner stators together. Specifically, the retainer works to join the outer stator and the inner stator together and also to tightly hold the outer periphery of the outer stator and the inner periphery of the inner stator, thus minimizing misalignment of the outer and inner stators in axial and radial directions there of.

The outer stator has a first multi-phase coil wound thereon so as to form magnetic poles upon energization of the first multi-phase coil. The inner stator has a second multi-phase coil wound thereon so as to form magnetic poles upon energization of the second multi-phase coil. The number of the magnetic poles formed by the outer stator is equal to the number of the magnetic poles formed by the inner stator. Each of the magnetic poles formed by the outer stator is located at the same circumferential position as and has an opposite polarity to a corresponding one of the magnetic poles formed by the inner stator. The rotor has yoke portions each of which radially extends so as to form a magnetic flux passage magnetically connecting the outer and inner stators.
