Abstract

The utility model discloses a rotor punching sheet for a wind-driven electricity generator. The rotor punching sheet for a wind-driven electricity generator comprises a punching sheet body provided with a bearing hole, wherein a number of wire insertion grooves are uniformly distributed on the punching sheet body, the opening part of each wire insertion groove is smaller than the bottom part of each wire insertion groove in size, two sides of the bearing hole are provided with a first mark groove and a second mark groove, and the bottom part of the first mark groove is provided with a half-round recessed part. The number of the wire insertion grooves is 72 to 96. If the rotor punching sheet of the utility model is used in a wind-driven electricity generator, electricity generating efficiency of the wind-driven electricity generator can be effectively improved.

Description

The wind-driven generator rotor punching

Technical field

The utility model relates to a kind of wind-driven generator rotor punching, belongs to an 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.

Generator rotor core is that the rotor punching by monolithic is formed by stacking, and coil winding is on rotor.The generator of different model has the stator punching of the unified size of different model, and rotor punching is the key components and parts in the generator rotor 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 rotor 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 rotor punching, to improve the efficient of wind-driven generator.

The utility model realizes that the technical scheme of above-mentioned purpose is: the wind-driven generator rotor punching, comprise the punching body, the punching body is provided with dead eye, be evenly distributed with some line embedding grooves on the punching body, the size of the oral area of described line embedding groove is less than the size of bottom, be provided with the first mark groove and the second mark groove on the dead eye both sides, a semicircular recess is arranged at the bottom of the described first mark groove.

As the further setting of such scheme, the quantity of described line embedding groove is 72 ~ 96.

The beneficial effects of the utility model are: wind-driven generator uses rotor punching of the present utility model, can effectively improve the generating efficiency of wind-driven generator.
