Abstract:
1. A dynamoelectric rotor comprising: a pole core having: a bobbin having: a field coil that is wound on said bobbin housed in said coil housing space by winding a winding start end thereof onto said output wire securing portion, winding on said drum portion, and winding a winding finish end thereof onto said output wire securing portion; 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; an annular body that is made of an insulating resin, that is fixed to a portion of said shaft projecting outward at a first end of said pole core, and that has a radially-projecting flange portion at an end near said pole core; a pair of slip rings that are fixed to outer circumferential portions of said annular body so as to be separated axially; and a pair of connecting terminals that are disposed on said annular body such that first ends are respectively connected to said pair of slip rings and second ends project radially outward from said radially-projecting flange portion, wherein said coil winding start end and winding finish end of said field coil are led out toward said annular body from said output wire securing portion within a range that is less than or equal to one magnetic pole pitch circumferentially, and respectively connected to projecting portions of said pair of connecting terminals.
