On the Influence of the Nonuniformity of Remagnetization of Fe–3% Si Anisotropic Electrical Steel on Magnetic Loss in Rotating Magnetic Fields

详细

Abstract—Different levels of magnetic loss for the rotational remagnetization are found on Fe–3% Si samples cut from different parts of anisotropic electrical strip steel (AES) with a 〈001〉 {110} edge texture. Based on the analysis of the magnetic-loss components and the frequency variation of the permeability of samples, it is shown that the difference is caused by different degrees of texturization. An effective reduction in magnetic loss due to rotational remagnetization of AES can be achieved by applying locally deformed zones onto areas with the maximum degree of texturization.
