The efficiency was measured under a load test using the inverter drive to verify the loss reduction effect when the winding changeover was applied. The stray load loss of series connection with a 184V synchronous 3 pulse could be reduced by 78% compared to the parallel connection with a 92V asynchronous pulse width modulation. Moreover, it was confirmed that the efficiency of the series connection is improved by approximately 4.4% compared to the parallel connection. Based on the above, it is confirmed that switching between series and parallel connections using a winding switcher can increase the efficiency of induction motors.本誌: 電気学会論文誌D（産業応用部門誌） Vol.144 No.11 （2024）本誌掲載ページ: 753-760 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/144/11/144_753/_article/-char/ja/
