利用统计损耗理论分析了机械应力对电工钢片磁损耗的影响。本文的重点是研究超损耗分量随外加应力的变化及其与磁滞损耗的关系。通过在感应水平、频率和应力的各种组合下进行全面测量，验证了该模型及其相关性。据发现，多余的损失，可以建模与足够的精度，通过它们的相关性在很宽的范围内的应力，频率和磁通密度的磁滞损耗。
Effect of mechanical stress on the magnetic loss of electrical steel sheets is analyzed utilizing the statistical loss theory. The focus of this paper is on the variation of the excess loss component with the applied stress and its correlation with the hysteresis loss. The model and its correlation are validated by performing comprehensive measurements at various combinations of induction levels, frequencies, and stresses. It is found that the excess losses can be modeled with sufficient accuracy by their correlation with the hysteresis losses over a wide range of stresses, frequencies, and flux densities.
