Abstract: The efficiency of electrical machines depends among other things on
the specific total loss of electrical steel the core is made of. Hence, a
better understanding of the loss mechanism can improve the efficiency of
machines. In order to analyze the specific total loss of electrical steel
grades, they were separated into three components: the hysteresis loss
component and both the classical and additional eddy current loss components.
The relationship between loss components and direction of magnetization was
analyzed. The aim of this paper is to provide a contribution to a better
understanding of magnetic specific total loss in electrical steel sheets.
Keywords: Specific total loss, hysteresis loss, classical eddy current, additional loss, electrical steel sheets
