50WW470 Cold Rolled Silicon Steel Coil non-oriented silicon steel sheets 0.5mm
The design Bm of oriented silicon steel is as high as 1.7-1.80T, close to the value of B8, so B8 is taken as the magnetic susceptibility protection value.The motor design Bm is about 1.5T, which is close to the B50 value of cold-rolled unoriented silicon steel sheet. Therefore, B50 is taken as the magnetic induction guarantee value of cold-rolled unoriented silicon steel.The magnetic inductance of hot rolled silicon steel is lower, and B25 is usually taken as the guarantee value.
