本文介绍了一种根据几个宏观实验计算无取向钢板在正弦磁化下的铁损的方法，并考虑了饱和和磁滞。从宏观角度考虑，铁耗可分为磁滞损耗和涡流损耗两部分，分别采用坡印亭矢量和麦克斯韦方程计算。这些损失的研究由Preisach模型的磁滞模拟相关的非线性系统方程的决议。计算适用于无取向的Fe-Si钢板和Epstein装置上获得的实验结果进行了比较，在很宽的频率和磁通密度范围。
This paper describes a method of calculating the iron losses from few macroscopic experiments, for non-oriented steel plate with sinusoidal magnetisation, taking into account saturation and hysteresis. With macroscopic considerations, iron losses are calculated using Poynting vector and Maxwell's equations, and can be separated into two components: hysteresis and eddy current losses. These losses are studied by resolution of the non-linear system equation associated to hysteresis simulation by the Preisach model. Calculations are applied to non-oriented Fe-Si steel plates and compared with experimental results obtained on Epstein apparatus for a wide range of frequencies and flux densities.
