Some Properties of Factors of Specific Total Loss Components in Electrical Steel

One of the most important parameters of electrical steel sheet is specific total loss. In order to analyze the specific total loss, seven electrical steel grades were separated into three components: the hysteresis loss component and both the classical and additional eddy current loss components. Parameters used for the description of loss components in statistical loss models were analyzed and found to be dependent on electrical steel grade, and hence, on grain orientation. The aim of this paper is to provide a contribution to the better understanding of magnetic specific total loss in electrical steel sheets.
