Motor, transformer, relay iron core, commonly used silicon steel sheet, what material is often used?
The addition of silicon increases the resistivity and maximum permeability of the iron, reduces the coercivity, the core loss (iron loss) and the magnetic aging. Mainly used to make transformers, motors and generators iron core. The world's silicon steel sheet production accounts for about 1% of the total steel (see precision alloy).
Silicon steel sheet, English name is silicon steel sheets, it is a kind of carbon containing very low silicon iron soft magnetic alloy, generally contain silicon quantity is 0.5 ~ 4.5%.
The magnetic circuit of motor and transformer often adopts silicon steel sheets, its high permeability, low loss, saturation phenomenon.
The relay core is pure (grade DT3, DT4) motor is a low silicon non oriented silicon steel sheet (grade 35WW600,35BA470). With the requirements of transformer silicon steel sheet, small power requirements for non oriented silicon steel sheet (grade 35WW600,35BA470). For small losses, with small grain oriented silicon steel tablets (grades 30Q135, Z10).
