Non-oriented electrical steel coil for Ei Lamination Transformer Core R Silicon Steel Coil of Cold Rolled
What are the different types of electrical steel?
Electrical steel is classified into two types: non-oriented (NO)
electrical steel and grain-oriented (GO) electrical steel.
NO steel is widely used in rotating electrical machines (e.g., motors and generators)
in which the magnetization direction is rotated in the sheet plane.
What grade is electrical steel?
For all practical purposes, AK Steel Electrical Steels, from grades
M-15 to M-47, are nonoriented materials.
In other words, their magnetic properties with respect to the direction of rolling are primarily random.

The performance requirements of silicon steel are mainly:
1, low iron loss, which is the most important index of silicon steel sheet quality. Countries are graded according to iron loss, the lower the iron loss, the higher the grade.
2. The magnetic induction intensity (magnetic induction) is high under the strong magnetic field, which reduces the volume and weight of the motor and transformer core, saving silicon steel sheet, copper wire and insulating materials, etc.
3, the surface is smooth, smooth and uniform thickness, can improve the filling coefficient of the iron core.
4. Good punching performance is more important for the manufacture of micro and small motors.
5. The adhesion and weldability of the surface insulation film are good, which can prevent corrosion and improve the punching property.
