Patent ID: 7122934

Claim:
A rotating electric machine comprising a stator and a rotor disposed rotatably with respect to the stator via a clearance, wherein said stator has a stator core, a stator winding incorporated in the stator core, and a mold made of an insulating resin provided on the stator core, wherein said stator core is comprised of an annular yoke core and a plurality of teeth cores projecting from the yoke core in one radial direction, wherein said stator winding is comprised of a winding conductor wound on each of the plurality of the teeth cores via the insulating resin mold in a concentric winding manner, the insulating resin mold is installed on each of the plurality of the teeth cores by insert-molding and has a winding portion disposed closely on the surface of each of the plurality of the teeth cores, wherein the winding portion is a portion of the insulating resin mold on which portion the winding conductor is wound and the thickness of the winding portion is smaller than that of the portion other than the winding portion on the insulating resin mold, and wherein the plurality of the teeth iron cores, being formed separately from the yoke core, have the insulating resin mold installed thereon by insert-molding and are fitted on the yoke core with the winding conductor wound on the winding portion, wherein grooves are formed at the surface of each of the teeth, at which the insulating resin is inserted and around which the stator winding is wound, and at both surfaces of a core laminated thick surface formed by laminating the iron cores in such a manner as to be continuously formed from one laminating end of the iron core to the other laminating end of the iron core, and further, in such a manner that a position in the radial direction of the stator at one surface are different from that at the other surface.
