Compared with other materials such as ferrite and amorphous materials, the iron core can be made very small due to the high saturation magnetic induction and high magnetic permeability of the 3% Si-Fe thin strip. Because it is a cold-rolled strip, it has a smooth surface, small differences between the same plates, good plate shape, and good processing performance. It can be made into iron cores of various shapes and specifications such as CD type, ring type, and rectangular type. It has a wide range of applicationsand wide frequency range (50H-20KH). Use of Non-oriented Silicon Steel Non-oriented silicon steel is mainly used in motors: Gap motors (water pumps) mainly use cold-rolled, non-oriented, uncoated silicon steel. Motors for electric welding machines are divided into DC motors and AC motors. DC motors can use uncoated cold-rolled silicon steel, and AC motors mainly use coated 600 non-oriented silicon steel. Air compressor, and pneumatic pump motors can also use uncoated cold-rolled silicon steel. The micro motors used in small household appliances mainly use non-oriented 470. Most of the motor used in CNC machine tools is 470. Motors for air conditioning compressors mainly use 600, 800, 1000, and 1300 silicon steel. Air compressor Silicon steel occupies a very important position in electrification construction.
