Design and Analysis of the 45kW-Class Magnetic Geared Permanent Magnet Synchronous Motor for Traction of Tram Vehicles

The magnetic geared permanent magnet synchronous motor (MG-PMSM) is a PMSM that has two rotors with different rotation speeds and includes the function of gear. design studies 45kW-class MG-PMSM are conducted for application driving system tram. In this research, first, to derive detailed model tram, analysis characteristics according stator winding method was performed. After selecting can reduce size MG-PMSM, topologies were applied determine number poles, outer rotor pole pieces, inner poles MG-PMSM. A derived by applying topology minimize it confirmed required performance satisfied through electromagnetic analysis. addition, 4.5kW-class small-scaled prototype concentrated manufactured verify validity analytical model, verification
