Abstract

The invention relates to an acid-resistant silicon steel sheet for a wind generator rotor. The acid-resistant silicon steel sheet comprises a silicon steel sheet body, wherein the silicon steel sheet body is of a ring structure with a center hole (3); the ring structure comprises an outer ring (1) and an inner ring (2); first fan-shaped grooves (4) are formed in an inner ring area of the silicon steel sheet body; second fan-shaped grooves (6) are formed in the area between an inner ring (2) and an outer ring (1); installation holes (5) are formed in the areas between the adjacent first fan-shaped grooves (4); and the surface of the silicon steel sheet is coated with an acid-resistant coating. The acid-resistant silicon steel sheet for the wind generator rotor is light in weight, low in material consumption, high in energy conversion efficiency and good in acid resistance.

Description

technical field [0001] The invention relates to a silicon steel sheet. It 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 the wind force and convert it into electric energy through the nose; 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 rotor is formed by stacking and pressing multiple solid silicon steel sheets. Since the rotor keeps rotating during operation, the solid silicon steel sheet rotor is too bulky, requires many consumables, and has low energy conversion efficiency. [0003] The existing silicon steel sheet cannot effectively resist acid and cannot meet the needs of customers. Contents of the inv...
