Material-saving silicon steel sheet

Abstract

The invention relates to a material-saving silicon steel sheet. The material-saving silicon steel sheet is characterized in that the cross section of the material-saving silicon steel sheet is in a buckle shape, the material-saving silicon steel sheet comprises an E-shaped structure(5) and an I-shaped structure (4), the E-shaped structure(5) comprises a long edge (1) and three short edges (2), and the length of the long edge (1) of the E-shaped structure is twice of the length of the short edges (2). By the material-saving steel silicon sheet, the material can be utilized very well during production and cutting process, and waste is prevented; meanwhile, by improving the material of the silicon steel sheet, the iron loss value of the silicon steel sheet is reduced, the magnetic induction intensity of the silicon steel sheet can also be remarkably improved, the problem of mutual conflict between processes of reducing the iron loss and improving the magnetic induction in the prior art is solved, and the magnetic performance of the silicon steel sheet is remarkably improved; and the silicon steel sheet has low loss and high magnetic induction, thus, the consumption can be reduced, power can be greatly saved, and the silicon steel sheet has good economic and social benefits.

Description

technical field [0001] The invention relates to a silicon steel sheet, in particular to a silicon steel sheet which saves material during cutting, and 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] The traditional silicon steel sheets for electric motors have C-shaped or E-shaped cross-sections, which cannot make good use of materials during the production and cutting process, resulting in a lot of waste. At the same time, the iron loss value of the previous silicon steel sheet is relatively high, which cannot meet the increasingly high requirements of the wind turbine stator.
