Claims

[Scope of utility model registration request]

A housing is configured to support a stator around which a stator coil is wound, and a rotating shaft rotatably supported by the housing has a plurality of core portions equally spaced in the circumferential direction on the inner side of the stator. In an excitation type alternator with a fixed rotor, a first passage is bored in the center of the rotating shaft to guide cooling lubricating oil, and the inner end is communicated with the first passage while the outer end is connected to the first passage. An excitation type alternating current generator characterized in that a plurality of second passages are opened between the core parts and extend in the radial direction of the rotating shaft, and are bored in the rotating shaft and the rotor.
