Abstract
Disclosed in the utility model is a generator stator that comprises a stator iron core formed by lamination of stator punching sheets and an enamelled wire wound at the stator iron core. The stator punching sheets are circular ones; circular holes are arranged at the centers of the punching sheets; a plurality of gullets in rectangular shapes are arranged at the circular holes; and protruding teeth are symmetrically arranged at two side walls of the inner sides of the gullets. Buckling piece grooves that are concaved inwardly are arranged at the outer sides of the stator punching sheets; welding grooves are arranged at the sides of the buckling piece grooves; and ventilation holes are arranged at the stator punching sheets. After a plurality of stator punching sheets are laminated to from the stator iron core, the ventilation holes form a penetrating ventilation channel. Buckling pieces are arranged in the buckling piece grooves and are welded to the stator iron core by the welding grooves. According to the utility model, the welding grooves are arranged to weld and fix the stator punching sheets, so that insulation resistance between the punching sheets is improved and the magnetic conduction performance is enhanced. The ventilation holes are arranged at the stator punching sheets; and the stator iron core with the structure enables the base welding process to become simple, thereby reducing the manufacturing cost of the generator. Besides, the cooling capability of the stator punching sheets is also improved and the weight is reduced.
Description
Technical field
The utility model relates to generator unit stator.
Background technology
Self-clinching technology is generally adopted in existing stator punching crimping, because generator generally adopts the annealing orchidization method that eliminates stress to improve towards magnetic property, the part decomposition unavoidably appears in coating for silicon steel sheet in the heat treatment process of annealing.While is tighter owing to self-clinching punching lamination, fills in the annealing later stage to be difficult to form effective orchidization film in the steam course, thereby punching lamination insulation resistance is reduced, and influences the punching magnetic conduction, the impaired increase of motor, decrease in efficiency.In addition, stator punching is by being provided with teeth groove with winding around in endoporus, and the zone of stator punching body does not have the zone of vacancy, and radiating effect is poor, and weight is big.
The utility model content
The technical problem that the utility model mainly solves provides a kind of generator unit stator.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of generator unit stator is provided, comprise the stator core that is overrided to form by stator punching and the enamelled wire that is wrapped on the stator core, described stator punching is circular punching, its center has circular hole, described circular hole is provided with a plurality of teeth groove, and described teeth groove is rectangular, and the inner two side of teeth groove is provided with double wedge symmetrically; The outside of stator punching is provided with the cramp groove that caves inward, and is provided with welding groove at the side of described cramp groove, is provided with ventilation hole at stator punching; After the multi-disc stator punching laminated into stator core, described ventilation hole formed the vent passages that connects, and is provided with cramp in the described cramp groove, and cramp is welded on the stator core by welding groove.
Wherein, described cramp groove is provided with eight, is symmetrically distributed in the outer rim of described stator punching.
Wherein, described ventilation hole is polygon or circle.
Wherein, described enamelled wire is flat type copper wire.
The beneficial effects of the utility model are: it is fixing with stator punching welding that welding groove is set, and this is easy to form effective orchidization film in blueization of annealing process, improve punching lamination insulation resistance, the raising magnetic property, reduce impaired, the raising electric efficiency; Stator punching is provided with ventilation hole, the stator core of this structure can save 6 or 8 muscle of the inner surface welding of casing, make the support welding procedure simple, also make generator towards the technological development that lacks chipless, reduced the generator manufacturing cost greatly, ventilation hole also makes the stator punching heat-sinking capability be improved, and has alleviated weight.
