ABSTRACT:
A permanent-magnet generator rotor comprising a first rotor shaft end portion having in the axial center a hollow portion through which a bolt is passed; a second shaft end portion having in the axial center a hollow portion and a bearing portion through which the bolt is passed. A magnetic cylindrical body is sandwiched between the first and second shaft end portions. The permanent-magnet generator rotor includes the magnetic cylindrical body fixed between the first and second shaft ends, a permanent magnet held on the outer circumferential surface of the magnetic cylindrical body; a non-magnetic cylindrical body shrink-fit onto the outer circumferential surface of the permanent magnet; a stator disposed around the permanent magnet; and the bolt penetrating through the first and second shaft ends; the hollow portions in the generator, and the magnetic cylindrical body.
