要約(英語): The iron loss of an electrical steel sheet increases by compressive stress. The major factors of this phenomenon are reported to be the increase of the hysteresis loss and the abnormal eddy current loss. To evaluate the abnormal eddy current loss, we have to know the accurate classical eddy current loss because the abnormal eddy current loss can be calculated by taking difference between the total eddy current loss and the classical eddy current loss. In this paper, for accuracy improvement, we report the evaluation of the classical eddy current loss considering the skin effect change depending on the permeability change caused by applied compressive stresses.
