    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 rotor securing arrangement for directly or indirectly securing a rotor to a shaft. The rotor has at least one through hole along a axial direction of the rotor. A second hole diameter of the at least one through hole at either or both of axial ends of the rotor is greater than a first hole diameter of the at least one through hole at a portion other than the axial ends of the rotor. The rotor securing arrangement includes a first securing member corresponding to the first hole diameter of the at least one through hole, and a second securing member corresponding to the second hole diameter of the at least one through hole. The first securing member is configured to directly or indirectly secure the rotor to the shaft with at least a portion of the second securing member between the first securing member and the rotor.

    Abstract: A detection part of a temperature detection element is mounted to ends of drawn portions which are further protruded in the axial direction than coil end portions. The detection part and the ends of the drawn portions provided with the detection part are covered with a covering member. The ends of the drawn portions provided with the detection part and covered with the covering member are inserted into a through hole of a wall member which is disposed so as to axially face an axial end face of a stator core. In this case, the detection part is located at a position deeper (on the rear side) than a position of a stator core side opening of the through hole.

    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.

    Abstract: A double-stator rotating electric machine includes a rotor and a pair of outer and inner stators. 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.

    Abstract: The synchronous motor includes a rotor including a rotor core constituted of segment poles disposed in a ring and a stator including a stator core disposed radially outward or inward of the rotor with a gap therebetween and a multiple-phase stator winding wound on the stator core. Each of the segment poles has a magnetic salient pole characteristic. The rotor is rotated in synchronization with a rotating magnetic field generated when the multiple-phase stator winding is applied with a multiple-phase AC voltage. The lamination thickness as an axial length of the stator core is shorter than the lamination thickness as an axial length of the rotor core.
