Description

Technical Field

[0002] At present, the core of linear motors is mainly made of non-oriented silicon steel sheets. Silicon steel has the characteristics of high magnetic permeability, low coercive force, large resistivity, low iron loss, etc., and is widely used in motors and transformers. Silicon steel is divided into oriented silicon steel and non-oriented silicon steel. The grains of oriented silicon steel are basically in one direction, while the grains of non-oriented silicon steel are arranged in a disorderly manner. Compared with non-oriented silicon steel, oriented silicon steel has higher magnetic permeability, smaller magnetic resistance, and lower iron loss in the rolling direction, and its magnetic properties are better than those of non-oriented silicon steel; however, the magnetic properties of oriented silicon steel perpendicular to the rolling direction are much lower than those of non-oriented silicon steel sheets.
