High permeable high resistive Silicon Steel with the small hysteresis and eddy current loss

     According to the use, silicon steel sheet can be divided into motor silicon steel sheet (the mass fraction of silicon is usually less than 2.5%, and the thickness is generally 0.3ram and transformer silicon steel sheet (the mass fraction of silicon is usually 2.3%~3.3%, and the thickness is generally O.35mm); According to the production method, it can be divided into hot-rolled silicon steel sheet and cold-rolled silicon steel sheet, and cold-rolled silicon steel sheet can be divided into oriented silicon steel sheet used to manufacture transformer and non-oriented silicon steel sheet used to manufacture motor according to the degree of grain orientation.

     According to the working conditions, it can be divided into silicon steel sheets used in strong magnetic fields mostly used in the power industry, which is the most common and largest amount and silicon steel sheets used in weak magnetic fields mostly used in the telecommunications industry, as well as silicon steel sheets used in power frequency and silicon steel sheets used in high frequency.In order to reduce the eddy current loss at high frequency, the thickness of O.1~0.2ram is usually used, and the thickness of the silicon steel sheet used in the pulse transformer can be as thin as 0.05mm.
