要約(英語): Magnetic-geared motors (MGMs) have attracted attention owing to their ability to offer higher torque densities than conventional permanent magnet (PM) motors. 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.
