摘　　要：首先介绍了铁耗分立计算模型,随后采用标准规定的用爱泼斯坦方圈测硅钢片损耗的方法对铁磁材料进行损耗实验,对实验结果数据进行回归分析计算出了铁耗分立模型中的未知参数,并分析了参数的特性。将其应用于铁耗计算中,所得出的结果非常接近于实际值。在此基础上进一步分析了铁耗各分量随频率、磁密变化的规律。结论对于铁耗分析有非常重要的参考意义。The paper presents loss separation model, then the method of iron loss measurement by means of an Epstein frame prescripted in standard is employed to the loss experiment, parameters in the model are calculated through a method called regression, using the experiment result. Parameters are used in predicting iron loss, there is hardly any discrepancy between the computed and the measured re- suits. In the meantime the relationship between the loss contribution and frequency, flux density is discussed based on the computed result. Conelution is very valuable for the loss prediction.
