When the rotor is rotating, the scoop-up part scoops up an oil stored in the housing, the oil and inside air are compressed in the oil container, and the exhaust outlet exhausts the oil and compressed air to the coil end of the stator. The housing stores the oil at a lowermost side thereof so that the scoop-up part and the exhaust outlet are immersed in the oil.

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.
