Abstract In this research, a design model derivation study is conducted to apply the 45kW-class MG-PMSM to the Wireless Tram driving system composed of a conventional induction motor and a mechanical reducer. First, a comparative analysis of electromagnetic characteristics according to a distributed winding and a concentrated winding method among the stator winding methods applied in general PMSM is performed. Next, a characteristic comparison analysis according to the magnetization direction of the permanent magnet of the inner rotor is performed. Finally, a stator winding method suitable for miniaturization and high efficiency of the 45kW-class MG-PMSM is selected
