Abstract
The utility model discloses a stator punching sheet for a wind-driven electricity generator. The stator punching sheet for a wind-driven electricity generator comprises a punching sheet body, wherein a number of wire-winding teeth are uniformly arranged at an inner ring of the punching sheet body, a number of fastening sheet grooves are uniformly arranged at an outer ring of the punching sheet body, a side of the top end of each wire-winding tooth is provided with a recessed part having an arc bottom, the other side is provided with a wedge-shaped protrusion part, and an included angle formed between the bottom edge of each fastening sheet groove and each side plate is between 45 degrees and 75 degrees. After the rotor punching sheet of the utility model is used in the wind-driven electricity generator, efficiency can be effectively improved.
Description
Technical field
The utility model relates to a kind of wind-driven generator stator punching, belongs to the accessory of wind-driven generator.
Background technology
Wind-driven generator is widely used in the generating at present as a kind of clean energy resource, but existing wind-driven generator ubiquity inefficient defective, can not reach purpose efficiently.
Electricity generator stator core is that the stator punching by monolithic is formed by stacking, and coil winding is on motor stator.The generator of different model has the stator punching of the unified size of different model, and stator punching is the key components and parts in the electricity generator stator core, its material, interior round size, outside dimension, flute profile size, what etc. efficiency of motor is had direct influence.And the wind-driven generator that uses in the market, oneself can't reach the purpose that improves generator efficiency its stator punching.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of wind-driven generator stator punching, can improve the efficient of wind-driven generator.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of wind-driven generator stator punching, comprise the punching body, evenly be provided with some coiling teeth at punching body inner ring, evenly be provided with some cramp grooves in punching body outer ring, top one side of described coiling tooth is provided with the recess of an arcuate bottom, opposite side is provided with the protuberance of a wedge shape, and the base of described cramp groove and the angle α between the side plate are between 45 ° ~ 75 °.
As the further setting of such scheme, the quantity of described coiling tooth is 72 ~ 96.
As the further setting of such scheme, the quantity of described cramp groove is 8 ~ 16.
The beneficial effects of the utility model are: after wind-driven generator uses stator punching of the present utility model, can effectively raise the efficiency.
