Performance requirements for one phase EI silicon steel sheet with holes with holes

1 Iron loss is low, which is the most important indicator of the quality of silicon steel sheet. Countries are divided according to the iron loss value, the lower the iron loss, the higher the grade.

2 The magnetic induction intensity (magnetic inductance) is high under a strong magnetic field, which reduces the volume and weight of the core of the motor and the transformer, and saves silicon steel sheets, copper wires and insulating materials.

3 The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the iron core.

4 punching is good, more important for the manufacture of miniature, small motors.

5 The surface insulating film has good adhesion and weldability, and can prevent corrosion and improve chipping property.

6 Basic non-magnetic aging.

The one phase EI silicon steel sheet with holes with holes generally increases in silicon content, and the iron loss, chipping property and magnetic induction are lowered, and the hardness is increased. The higher the operating frequency, the greater the eddy current loss, and the thinner the silicon steel sheet should be.
