Abstract

The invention relates to a stator silicon steel plate which is characterized in that the stator silicon steel plate comprises a stator silicon steel plate body (1); the inside of the stator silicon steel plate body (1) is provided with a hole for mounting a coil; the outside of the stator silicon steel plate body is provided with extending fins (2) for heat radiation; and the stator silicon steel plate body (1) has a square or octagonal structure. According to the stator silicon steel plate, a material can be well used in a production cutting process, thereby preventing wastage; and furthermore through improving the material of the silicon steel plate, an iron loss value of the silicon steel plate is reduced; magnetic induction strength of the silicon steel plate can be remarkably improved; a problem of contraction between iron loss reduction and magnetic inductance increase is settled; and magnetic performance of the silicon steel plate is remarkably improved. Because of low loss and high magnetic inductance of the silicon steel plate, consumption can be reduced, thereby saving a large amount of electric power. The stator silicon steel plate has high economic benefit and high social benefit.

Description

technical field [0001] The invention relates to a silicon steel sheet, in particular to a stator silicon steel sheet, 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 outer layer of the stator silicon steel sheet 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 iron loss value of the previous silicon steel sheet is relatively high, which cannot meet the increasingly high requirements of the wind turbine stator.
