Abstract

This paper presents a comparison between single-phase 12S-6P and three-phase 12S-10P field excitation flux switching machine (FEFSM) with non-overlap windings and salient rotor. Based on the previous designs, three-phase FEFSM and single-phase FEFSM have been developed with the overlap windings between armature and FEC which create problems of high end coil, increase the size of the motor and high copper losses. Moreover, the previous designs has odd number of pole caused unbalance magnetic forces. Therefore, a single-phase 12S-6P FEFSM and three-phase 12S-10P FEFSM with non-overlap windings and salient rotor is introduced to reduce the coil end problem. In this study, the operating principle of single-phase and three-phase salient rotor is also investigated. Then, flux line, flux distribution, induced voltage, torque and power versus speed validated with 2D-finite element analysis. Finally, the comparison of torque and power versus speed between two designs is highlighted. As a conclusion, three-phase 12S-10P FEFSM design is much better because at the based speed of 3597r/min, torque obtained is 13.5Nm, while the maximum power achieved is 3.2kW.
