However, to drive motors at high speeds, the operating frequency must be increased, which increases in harmonic losses, primarily iron loss and AC copper loss. Therefore, harmonic losses must be quantitatively evaluated with high accuracy at the design stage. In this study, the validity of the method for evaluating the AC copper loss during high-speed operation is examined by comparing the difference between analytical values and evaluation formulas based on the relationship between the harmonic components of the voltage and current and slot shape.本誌: 電気学会論文誌D（産業応用部門誌） Vol.144 No.9 （2024）本誌掲載ページ: 671-678 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/144/9/144_671/_article/-char/ja/
