PROBLEM TO BE SOLVED: To provide a so-called Lundell-type generator capable of avoiding occurrence of an eddy current in a rotor core without requiring a complicated structure.SOLUTION: The generator comprises a stator 10, a rotary shaft 20, first and second rotor cores 30A and 30B, and a rotor coil 40. Each of the rotor cores 30A and 30B include a base part 32 and a plurality of rotor magnetic pole parts 34 axially extending from the base part 32, and the rotor coil 40 is disposed inside. Each of the rotor cores 30A and 30B is formed from a plurality of unit plates 60 which are mutually laminated in an axial direction. The unit plates 60 integrally include substrate portions 62 which are mutually laminated and form the base parts 32, and a plurality of magnetic pole plate portions 64 which are mutually laminated and form the rotor magnetic pole parts 34. |
