Application analysis of silicon steel sheet iron core
A material with a large amount of magnetic materials for 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.
