Description

Wire frame of motor stator of motorcycle Technical Field The utility model relates to the technical field of motor of motorcycles, in particular to a wire frame of a motor stator of a motorcycle. Background The magneto is mainly composed of a stator and a rotor, wherein the stator comprises a stator core and a coil, the stator core is usually composed of a plurality of stator punching sheets which are overlapped and riveted together, the stator core is composed of a mounting part in the middle, the outer edge of the stator punching sheet is uniformly distributed with T-shaped winding teeth, the outer edge of the iron core formed by overlapping is formed into T-shaped winding teeth, then insulating materials are injection molded on the outer surface of the iron core, and finally the coil is wound on the winding teeth on the outer edge of the stator core to form the magneto stator. The stator punching sheet of the existing stator core is an integrated piece formed by stamping, a large amount of materials are punched out, the utilization rate of the materials is low, and the material cost is high. The utility model patent with the publication number of CN203166639U provides a magneto stator core, which comprises a stator punching sheet group, baffle punching sheets and an insulating framework which are correspondingly overlapped, wherein the main body part of the stator punching sheet is octagonal, a positioning hole is arranged in the middle of each side of the stator punching sheet, a T-shaped winding tooth is arranged in the middle of each side of the stator punching sheet, the baffle punching sheets are arranged at two ends of the stator punching sheet group, the shape of each baffle punching sheet corresponds to that of the adjacent stator punching sheet, the insulating framework is coated on a winding tooth overlapped body formed by the stator punching sheet group and the baffle punching sheets, the stator punching sheets are formed by eight sub punching sheets which are mutually embedded, the stator punching sheets are embedded through dovetail grooves, the dovetail grooves are arranged on the connecting line of the corners of the octagon and the centers of the positioning holes, one end of each sub punching sheet, which is close to the positioning holes, is provided with an anchor hole, so that the combination tightness between the sub punching sheets is improved, and the overlapping assembly of the stator punching sheets is convenient.
