How to define the brand of electrical silicon steel sheet, which is common in motors and generators?

At present, the silicon steel sheets used in motors and generators are mainly cold-rolled non-oriented silicon steel and cold-rolled oriented silicon steel, while the amount of hot-rolled silicon steel is less and less.

The brand of silicon steel sheet is determined according to the maximum iron loss of silicon steel, which is also the industry practice. Generally, the smaller the iron loss, the higher the price of silicon steel sheet. For example, the brand name of WISCO is 50WW3 10, which means that the thickness of silicon steel sheet is 0.5mm, and the maximum iron loss value cannot exceed 3. 1 watt per kilogram (w/kg) when the 50Hz magnetic flux density is 1.5 Tesla.

In addition, the thickness of cold-rolled silicon steel is mainly 0.35mm and 0.476mm(0.5mm).
