Silicon steel core

by:Transmart     2021-01-27

Silicon steel core is an iron-silicon alloy formed by adding a small amount of silicon (generally less than 4.5%) to pure iron, called silicon steel. This type of iron core has the highest saturation magnetic induction value of 20000Gs; because of their good magnetoelectric properties, easy mass production, low price, and small mechanical stress, they are widely used in the power electronics industry. Such as power transformers, distribution transformers, current transformers and other iron cores.

It is also the material with the largest amount of magnetic materials used in power transformers. Especially suitable for low frequency and high power. Commonly used are cold-rolled silicon steel sheet DG3, cold-rolled non-oriented electrical steel strip DW, cold-rolled oriented electrical steel strip DQ, suitable for medium and small power low-frequency transformers, chokes, and reactors in various electronic systems and household appliances , Inductor core, this kind of alloy has good toughness and can be processed by punching and cutting. The core has laminated and winding types. However, the loss increases sharply at high frequencies, and the general use frequency does not exceed 400 Hz.
