Abstract:
1. A dynamoelectric machine comprising: a rotor comprising: a stator that is disposed so as to surround an outer circumference of said rotor so as to form a predetermined air gap, a magnet holder that is held between circumferentially-adjacent claw-shaped magnetic pole portions of said pair of yoke portions, a receiving groove being recessed into an upper surface of said magnet holder so as to pass through in said axial direction; a permanent magnet that is mounted to said magnet holder by fitting together with said receiving groove so as to face an inner circumferential surface near a tip end of said claw-shaped magnetic pole portion; a magnet cover comprising: a resin material that fixes said permanent magnet and said magnet cover to said magnet holder by filling an adhesive space that is bounded by said permanent magnet, said magnet cover, and said receiving groove; and a resin injection aperture that is formed on said magnet holder so as to communicate between an external portion of said magnet holder and said adhesive space.
