摘要： 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.

摘要： The present invention provides a rotary electric machine that can achieve prompt restarting and that can also reduce eddy current loss by reducing eddy currents that flow through an outer circumferential surface of a boss portion of a pole core due to the changes in flux in field magnetic flux build-up during starting to enable prompt field magnetic flux build-up in response to a restarting command.
In a rotary electric machine according to the present invention, a first pole core body (17) and a second pole core body (21) are produced using solid cores, and first slits (25) are formed on outer circumferential surfaces of a first boss portion (18) and a second boss portion (22) at a uniform pitch in a circumferential direction so as to have groove directions oriented in an axial direction to disrupt pathways of eddy currents that flow on the outer circumferential surfaces of the first boss portion (18) and the second boss portion (22).
