Improving material characteristics and optimizing designs have been studied from the standpoint of efficiency improvement of electrical machinery and apparatus. Unfortunately, the local magnetic properties in the actual core were still not understood fully. The study of soft magnetic materials commonly used in rotating machines and three-phase transformers is very important for saving energy. This paper deals with analysis by FEM for iron losses considering vector magnetic properties. The authors define the tensor magnetic reluctivity and calculate it from the data measured with two-dimensional measurement method. This numerical method is applied to the direct magnetic loss analysis. As a result, it is shown that the calculated results using the method are in a good agreement with measured ones.
