Abstract
The invention relates to an insulated anticorrosive stator silicon steel sheet. The stator silicon steel sheet is characterized by comprising a silicon steel sheet body (1), wherein the thickness of the silicon steel sheet body (1) is 0.4-0.6mm, the length of the silicon steel sheet body (1) is 2,000m and the width of the silicon steel sheet body (1) is 1m; holes for installing coils are formed in the inner side of the silicon steel sheet body (1), and radiating extension fins (2) are arranged at the outer side; the silicon steel sheet body (1) is of a square or octagonal structure; and the surface of the silicon steel sheet body (1) is sequentially coated with an insulating layer (3) and an anticorrosive coating (4). According to the insulated anticorrosive stator silicon steel sheet and a heating method thereof, the heat dissipation degree is better and the high-power requirement can be met. Meanwhile, the surface of each silicon steel sheet is coated with the insulating layer and the anticorrosive coating, so that the insulativity and the corrosion resistance of the silicon steel sheet are improved. Meanwhile, an improved heating method is adopted by the silicon steel sheet, the procedure is simple, energy is saved and the cost is relatively low.
Description
technical field [0001] The invention relates to a silicon steel sheet, in particular to an insulating and anti-corrosion stator silicon steel sheet and a heating method thereof, belonging to the technical field of electromechanical. 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] The outer layer of the insulated and anti-corrosion stator silicon steel sheet and its heating method has no heat dissipation structure, and the stator made of it has the disadvantage of poor heat dissipation performance, which affects the working efficiency of the entire motor. At the same time, the insulation and anti-corrosion properties of silicon steel sheets in the past are relatively...
