  • Patent number: 8593029
    Abstract: Provided is a Lundell type rotating machine with high efficiency and high output, which has a rigid and magnetically advantageous magnet retention structure. A rotor iron core includes laminated magnetic-pole members mechanically and magnetically coupled to two laminated magnetic end plates, which extend in an axial direction so as to be brought into meshing engagement with each other to constitute a Lundell type rotor iron core, and permanent magnets provided between the magnetic-pole members. The magnetic-pole members are retained in predetermined positions between the magnetic end plates by dovetail grooves of a non-magnetic retention body over substantially the entire lengths. The permanent magnets are held in direct contact with the magnetic-pole members so as to be interposed therebetween. Thus, the magnet retention structure which is mechanically rigid and magnetically highly efficient even when increased in size can be obtained.

  • Patent number: 8546994
    Abstract: An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by ensuring outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on portions of yoke portions between respective circumferentially adjacent claw-shaped magnetic pole portions. Magnet holders are disposed so as to span over all of the trough portions on a pole core body at a rear end excluding a predetermined trough portion, and permanent magnets are held in each of the magnet holders. A field coil lead wire is led out from the rotor so as to pass through the trough portion over which a magnet holder is not disposed.

  • Publication number: 20130154410
    Abstract: In this hybrid automobile, a stationary field rotary electric machine is disposed between an engine unit and a transmission unit such that a rotor is linked directly to a crankshaft of the engine unit. A static yoke portion is disposed inside the rotor from a side near the transmission unit such that a field winding is positioned radially inside first and second claw-shaped magnetic pole portions, and a static yoke portion mounting pedestal holds an end portion of a large diameter portion of the static yoke portion near the transmission unit. A radial width of the field winding is narrower than a radial width of a small diameter portion of the static yoke portion onto which the field winding is mounted.

  • Patent number: 8304950
    Abstract: A dynamoelectric machine that can suppress increases in rotor inertia to extend belt service life and increase field magnetomotive force to increase output. In the dynamoelectric machine, first and second magnetic guidance members are fitted into first and second holding grooves that are disposed so as to extend axially on facing portions of first and second trough portions radially outside inner wall surfaces, and are disposed so as to span over first and second trough portions. First and second permanent magnets that are magnetically oriented in a reverse direction to a magnetic field that originates from a field coil are fitted into and held by interfitting grooves of the first and second magnetic guidance members so as to face inner circumferential surfaces near tip ends of second and first claw-shaped magnetic pole portions so as to have a predetermined clearance.
