Abstract:
1. A dynamoelectric rotor comprising: a Lundell rotor core having: a cylindrical boss portion; yoke portions respectively disposed so as to extend radially outward from two axial end edge portions of said boss portion; and a plurality of claw-shaped magnetic poles disposed so as to extend axially from outer peripheral portions of said yoke portions so as to intermesh with each other alternately; a field winding installed on said boss portion; and a plurality of linking structures made of a nonmagnetic material for linking a tip end portion and a root end portion of at least one adjacent pair of said claw-shaped magnetic poles, wherein one of said linking structures is mounted to each of said adjacent claw-shaped magnetic poles and adjacent pairs of said linking structures are placed in contact with each other or are joined together between said claw-shaped magnetic poles, wherein: said field winding is wound onto said boss portion so as to have a larger diameter than a root inside diameter of said claw-shaped magnetic poles and is placed in contact with an inner peripheral surface of at least one of said claw-shaped magnetic poles with an insulating member interposed.
