Abstract—This paper presents torque performance of three-phase permanent magnet flux switching motor (PMFSM) in out-runner segmented rotor for vehicular propulsion. This is the first time permanent magnet flux source and rotor segment are being employed in FSM design. PMFSM is electric machine in which both armature winding and permanent magnet source are located on the stationary stator only. The rotor is simple piece of sheet steel lamination to contain speed operation. The operating principle of proposed motor employing segmented rotor being used to modulate the polarity of the flux linkage in the stationary stator is confirmed with clear benefits. The 2D Finite Element Analysis (FEA) utilized the JMAG Designer version 14 to investigate four motors performances of the same stator pole in terms of magnetic flux linkages, cogging torque, induced back-emf and average torque. Results shows that 24s-14p motor can gauge optimum average torque of 263.5Nm and has high performance for in-wheel propulsion for long distance travels compared with conventional PMSM.
