Abstract

The invention relates to a stator of a wind power generator and a processing method thereof, comprising a stator body, the stator body is formed by stacking and pressing multiple silicon steel sheets (1) continuously, and the center of the silicon steel sheet (1) is provided with a perforation (2), characterized in that 54 slots (3) are evenly recessed on the silicon steel sheet (1) on the outer edge of the perforation (2), and the silicon steel sheet (1) is composed of 4 fan-shaped silicon steel sheet units (4 ) welded, the central angle of the silicon steel sheet unit (4) is 90°, the outer surface of the silicon steel sheet 1 is provided with a high magnetic permeability silicon coating, and the processing methods include stamping, lamination, injection molding nylon, enameled wire winding and dry. The silicon steel sheet of the present invention is welded by four fan-shaped silicon steel sheet units, so that a large amount of material will not be wasted when the silicon steel sheet of the stator of the wind power generator and its processing method are cut and formed, the processing method is simple, the work efficiency is high, and the labor intensity of the workers is low. , the overall quality is good, and the insulation effect is good.

Description

technical field [0001] The invention relates to a stator of a wind power generator and a processing method thereof, belonging to the field of electromechanical technology. Background technique [0002] A wind turbine consists of a nose, a swivel, an empennage, and blades. Every part is very important, and the functions of each part are: the blades are used to receive wind force and convert it into electrical energy through the nose; the empennage makes the blades always face the direction of the wind to obtain the maximum wind energy; The function of the empennage to adjust the direction; the rotor of the nose is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electric energy. The traditional wind turbine stator and its processing method are formed by stacking and pressing multiple silicon steel sheets that are integrally cut and formed. Since the silicon steel sheets have a ring structure, a lot of material is wasted when the silicon st...
