Abstract
A stator lamination of a generator comprises a stator lamination body formed by punching, laser and cutting. The inner side edge of the stator lamination body is provided with uniformly distributed coil embedding grooves, the outer side edge of the stator lamination body is provided with a plurality of uniformly distributed positioning grooves, a tension hole for overlapping laminations is arranged on the surface of the lamination body, a layer of water-soluble insulating paint is coated on the surface of the stator lamination body, each positioning groove is an embedding groove with an oblique angle relative to the outer side edge, and each coil embedding groove is an elongated embedding groove perpendicular to the inner side edge. The stator lamination has the advantages that the stator lamination is reasonable in structure, convenient to mount and low in manufacturing cost, the use efficiency of the generator can be improved and the like.
Description
Technical field
The utility model relates to a kind of stator punching of generator, belong to mechanism of power generation technology for making field.
Background technology
The critical piece of generator comprises rotor and stator or the like, and the punching structure of stator punching has wherein determined the utilance, manufacturing cost of stator material and to result of use of generator etc.Because some stator laminating structures of prior art exist certain irrationality, cause the service efficiency of generator low, manufacturing cost is high.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, the stator punching of generator easy for installation.
The purpose of the utility model is accomplished through following technical scheme; It comprises that one adopts the stator punching body of punching out or laser or excision forming; The inner side edge of said stator punching body is provided with the coil caulking groove that is uniformly distributed with; Outer side edges is provided with a plurality of detents that are uniformly distributed with, and the surface of punching body is provided with and is used for the overlapping tension hole of punching, scribbles one deck water-soluble insulating varnish on the surface of said stator punching body in addition.
Described detent is a kind ofly to be the caulking groove at an angle of inclination with respect to outer side edges, and described coil caulking groove is the strip caulking groove perpendicular to inner side edge.
The utlity model has rational in infrastructurely, easy for installation, low cost of manufacture can improve the characteristics such as service efficiency of generator.
Description of drawings
Fig. 1 is the structural representation of the utility model.
