Document Type and Number:
WIPO Patent Application WO/2014/203437
Kind Code:
A1
Abstract:
Provided is a so-called Lundell generator capable of avoiding eddy current occurring in a rotor iron core without requiring a complicated structure. The generator comprises a stator (10), a rotating shaft (20), first and second rotor iron cores (30A, 30B), and a rotor coil (40). The rotor iron cores (30A, 30B) have a base portion (32) and a plurality of rotor magnetic pole portions (34) extending from the base portion (32) along a shaft direction, and the rotor coil (40) is disposed inside the rotor iron cores (30A, 30B). The rotor iron cores (30A, 30B) are constituted by a plurality of unit plates (60) stacked on each other in a shaft direction. The unit plates (60) have base plate portions (62) stacked on each other to form the base portion (32) and a plurality of magnetic polar plate portions (64) stacked on each other to form the respective rotor magnetic pole portions (34), said base plate portions (62) and said magnetic polar plate portions (64) being integrally formed.
