Silicon steel sheet, also known as electrical silicon steel, is made of electrical steel as the main raw material and a certain proportion of silicon is added. Its main function is to reduce the magnetic loss and iron loss of electrical equipment such as motors, transformers, generators, and improve the efficiency and energy-saving performance of electrical equipment. The magnetic properties of the silicon steel sheet are very different from those of electrical steel, which has high magnetic permeability and low magnetization force, making the energy conversion of electrical equipment more efficient.
