Japanese Patent JP5506808

Kind Code:

B2

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.
