Anti-electromagnetic silicon steel sheet for wind generator stator

Abstract

The invention relates to an anti-electromagnetic silicon steel sheet for a wind generator stator. The anti-electromagnetic silicon steel sheet comprises a silicon steel sheet body (1) and is characterized in that the silicon steel sheet body (1) is formed by welding a plurality of fan-shaped silicon steel sheet units (2) with the same central angle; a plurality of wire slots (3) are recessed inward in inner edges of the silicon steel sheet units (2); the silicon steel sheet body (1) is equipped with a plurality of round ventilation holes (4); the round ventilation holes (4) encircle the center of the silicon steel sheet body (1) to form a single-circle or multi-circle arrangement structure; and a surface of the silicon steel sheet is coated with an anti-electromagnetic coating. According to the anti-electromagnetic silicon steel sheet for the wind generator stator, the silicon steel sheet body is formed by welding the plurality of fan-shaped silicon steel sheet units with the same central angle so that waste of a lot of materials is avoided when the anti-electromagnetic silicon steel sheet for the wind generator stator is cut for molding, and the anti-electromagnetic silicon steel sheet has an anti-electromagnetic function.

Description

technical field [0001] The invention relates to an anti-electromagnetic silicon steel sheet for a stator of a wind power generator, which belongs 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 is formed by stacking and pressing multiple pieces of silicon steel sheets that are cut and formed in one piece. Since the silicon steel sheets have a ring structure, a lot of material is wasted when the silic...

Problems solved by technology

The traditional wind turbine stator is formed by stacking and pressing multiple pieces of silicon steel sheets that are cut and formed in one piece. Since the silicon steel sheets are in a ring structure, a lot of material is wasted when the silicon steel sheets are cut and formed.

[0003] The existing silicon steel sheets cannot effectively prevent electromagnetic waves and cannot meet the needs of customers
