In this paper, dynamic reluctance mesh model (DRM) combined with an improved iron losses prediction model are presented to provide fast and accurate way to evaluate the iron losses for permanent magnet (PM) motors with pulsewidth-modulated power supply. A DRM model for high-speed train PM traction motor is first built. The magnetic field distribution for one cycle is then obtained using the DRM method...
Magnetic gears (MGs) have received extensive attention in the last decade. The flux-modulated machine (FMM) is one of the derived topologies from the MG. The existing FMMs which mostly adopt the radial-flux configuration suffer from a relatively low torque density compared with other MG-integrated machines. This paper proposes a novel axial-radial flux-modulated machine which has an improved torque...
Dynamic reluctance mesh method (DRM) combines the advantages of finite-element method(FEM) and magnetic equivalent circuit method. The attractive advantages of this method include as follows: less mesh units compared with FEM; higher computational accuracy than traditional magnetic equivalent circuit method. This paper presents modeling and analysis of permanent magnet synchronous motor using DRM...
