An MGM consist of a magnetic gear (MG) part and a PM motor part, which are shared one high-speed-rotor (HSR). An interior permanent magnet (IPM) type and a surface permanent magnet (SPM) type has been proposed as a structure of HSR. In the IPM-type HSR, the PM motor part and MG part are magnetically coupled to each other, which is called a magnetic interaction. However, the torque equation considering this magnetic interaction has not been studied thus far. This paper presents the torque equation of an IPM-type MGM (IPM-MGM). The torque equation considering the magnetic interaction is derived based on the proposed vector diagram, and the parameter identification is conducted by using a two-dimensional finite element method. Moreover, the validity of the torque equation is proved through comparison with experimental results.本誌: IEEJ Journal of Industry Applications Vol.10 No.6 （2021） Special Issue on “ICEMS 2020-Hamamatsu”本誌掲載ページ: 612-617 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/10/6/10_20012813/_article/-char/ja/ Show more
