0.35mm B35A550 Cold Rolled Silicon Steel Coil non-oriented silicon steel sheets

Core loss refers to the invalid electric energy consumed when the iron core is magnetized at ≥50Hz alternating magnetic field. It is simply called iron loss, also known as alternating loss, and its unit is W/kg.This kind of ineffective electric energy consumed due to various obstacles to the flux change, not only loses electric energy through the core heating, but also causes the temperature rise of the motor and transformer.The iron loss (PT) of silicon steel sheet includes hysteresis loss, eddy current loss (Pe) and abnormal loss (Pa).Low iron loss of silicon steel plate can not only save a lot of electric energy, but also prolong the operation time of motor and transformer, and simplify the cooling device.Due to the iron loss of silicon steel plate caused by the loss of electricity accounts for 2.5%~4.5% of the annual electricity generation in various countries, so the production of silicon steel plate always do everything possible to reduce the iron loss, and to iron loss as the most important index to assess the magnetic product, according to the iron loss value of the product as the basis for dividing the product brand.
