The invention relates to an insulated anti-corrosion silicon steel sheet for a wind driven generator rotor. The insulated anti-corrosion silicon steel sheet is characterized in that the insulated anti-corrosion silicon steel sheet comprises a silicon steel sheet body (1); the silicon steel sheet body (1) is of an annular structure with a central hole (2); a plurality of fan-shaped grooves (3) are evenly formed at the annular region of the silicon steel sheet body (1); the center angles of the fan-shaped grooves (3) face the center of the center hole (2); mounting holes (4) are formed in the annular region, wherein one mounting hole (4) is located between every two adjacent fan-shaped grooves (3); and the surface of the silicon steel sheet body (1) is sequentially coated with an insulated layer (5) and an anti-corrosion slayer (6). The insulated anti-corrosion silicon steel sheet for the wind driven generator rotor has the advantages of high energy conversion efficiency, high insulation and high anti-corrosion performance.
Description
technical field [0001] The invention relates to a silicon steel sheet, in particular to an insulating and anti-corrosion silicon steel sheet for a rotor of a wind power generator, which belongs to the field of electromechanical technology. Background technique [0002] Silicon steel sheet is a kind of silicon-iron soft magnetic alloy with extremely low carbon content. Generally, the silicon content is 0.5-4.5%. Adding silicon can increase the resistivity and maximum magnetic permeability of iron. It is mainly used to make various transformers, motors and The iron core of the generator. [0003] In the past, the rotor of a wind turbine was formed by stacking and pressing multiple solid silicon steel sheets. Since the rotor rotates continuously during operation, the solid silicon steel sheet rotor is too bulky, requires many consumables, and has low energy conversion efficiency. At the same time, the insulation and corrosion resistance of the conventional silicon steel sheets...
