Abstract:
1. A dynamoelectric rotor comprising: a pole core comprising: a columnar boss portion; yoke portions that are 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 pole portions that are disposed so as to extend axially from outer circumferential portions of said yoke portions so as to intermesh with each other alternately; a resin bobbin comprising: a cylindrical body portion; flange portions that are respectively disposed so as to extend radially outward from two axial end edge portions of said body portion; and an output wire securing portion that is disposed so as to extend radially outward from said flange portions, said resin bobbin mounted to said pole core by said cylindrical body portion fitted over said columnar boss portion; a rotor coil that is configured by winding a conducting wire onto said bobbin and in which an output wire that is led out from a wound portion of said conducting wire is wound onto said output wire securing portion; and a shaft that is inserted through a central axial position of said boss portion and that supports said pole core so as to be unable to rotate relatively, wherein at least a portion of a radially-outermost portion of said output wire securing portion is in contact with an inner circumferential wall surface of said claw-shaped magnetic pole portions.
