In this paper, the accuracy of the zooming method is validated by comparison with thorough analysis and the calculation speed in the zooming analysis is found to increase by 7.8 times that of thorough analysis.Moreover, the zooming method is applied to the analysis of the copper loss of a litz wire with respect to an interior permanent magnet motor rotating at high speed. The copper loss of the litz wire could be calculated within a practical computation time.本誌: IEEJ Journal of Industry Applications Vol.6 No.6 （2017） Special Issue on "ICEMS 2016-Chiba"本誌掲載ページ: 395-400 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/6/6/6_395/_article/-char/ja/ Show more
