DOUBLE-STATOR ELECTRIC ROTATING MACHINE

摘要

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.

1. A double-stator electric rotating machine comprising:
an outer stator which is equipped with an outer multi-phase winding; an inner stator which is equipped with an inner multi-phase winding, the inner stator being disposed inside the outer stator; a rotor which is disposed between the outer stator and the inner stator with gaps between itself and the outer stator and between itself and the inner stator; and a retainer which includes a connector which joints between the outer stator and the inner stator, the retainer being placed in contact with at least one of at least a portion of an outer peripheral surface of the outer stator and at least a portion of an inner peripheral surface of the inner stator to retain the outer and inner stators together.
