Silicon steel is a special electrical steel, also known as silicon steel sheet. It is composed of silicon and steel, the silicon content is usually between 2% and 4.5%. Silicon steel has low magnetic permeability and resistivity, and high resistivity and magnetic saturation induction. These properties make silicon steel an important application in electrical equipment such as motors, generators and transformers.
The main characteristics of silicon steel are low magnetic permeability and high electrical resistivity, which enable it to reduce eddy current loss and Joule loss in the iron core. Silicon steel also has a high magnetic saturation induction, making it able to withstand higher magnetic field strength without magnetic saturation.
The application of silicon steel is mainly concentrated in the field of power equipment. In the motor, silicon steel is used to manufacture the iron core of the motor to reduce eddy current loss and Joule loss and improve the efficiency of the motor. In generators and transformers, silicon steel is used to manufacture iron cores to increase magnetic saturation induction and reduce energy loss.
In general, silicon steel is an important electrical material with excellent magnetic permeability and resistance characteristics. It is widely used in the field of power equipment to improve the efficiency and performance of equipment
