Patent number: 8593029Abstract: 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.Type: GrantFiled: September 16, 2010Date of Patent: November 26, 2013Assignee: Mitsubishi Electric CorporationInventors: Masaya Inoue, Yoichi Kuroda, Masao Morita, Moriyuki Hazeyama

Patent number: 8546994Abstract: 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.Type: GrantFiled: October 1, 2008Date of Patent: October 1, 2013Assignee: Mitsubishi Electric CorporationInventors: Takeshi Mori, Masaya Inoue, Masao Morita, Hirokazu Akai, Toshiyuki Yoshizawa, Moriyuki Hazeyama, Shinji Nishimura, Kazunori Tanaka
