Abstract: A double-stator synchronous motor has a rotor, an inner stator and an outer stator. The rotor has segment-magnetic poles arranged in a ring shape. Magnetic poles formed in the inner stator and the outer stator face to each other in a same circumferential position. Each stator has q (q≧2) slots per pole and phase to disperse magnetomodive force. A radially minimum width Wr of each segment magnetic pole is within a range of 1.3q to 2.3q times of a minimum width Wt of outer teeth. A magnetic depth of a magnetic concave section formed in the segment magnetic pole is within a range of not less than an average width Ws of the inner slots. Because this suppresses demagnetization in the permanent magnets caused by stator magnetomotive force, ferrite magnets are used as buried magnets and magnetic-pole central magnets, and suppress the amount of neodymium magnet used in the rotor.

Abstract: In a multi-gap rotating electric machine, a side stator coil is received in a side space formed in a housing to connect radially inner and radially outer stator coils across a rotor. A cooling oil flow adjustment member is provided to adjust flow of cooling oil in the side space. The adjustment member has cooling oil guide channels formed on an uneven surface thereof facing the side stator coil. When viewed along a central axis of a rotating shaft: on an upper apart of the uneven surface which is located above the central axis, the cooling oil guide channels spread from a reference line to both sides of the reference line while extending downward; and on a lower part of the uneven surface which is located below the central axis, the cooling oil guide channels converge on the reference line from both sides of the reference line while extending downward.

Abstract: A rotating electrical machine has a housing, a stator having a stator core and a rotor having a rotor core and rotor side plates rotatably supported by the housing. The rotor core is arranged to have a gap between the end surfaces of the rotor core and the stator. Oil containers are arranged on at least one surface of the rotor side plate. Each oil container has a scoop-up part and an exhaust outlet formed on end sections thereof. 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.
