In this paper various techniques are applied to decrease cogging torque of overlap winding of permanent magnet flux switching machine (PMFSM) with 24-slot/16-pole. Due to its unique design PMFSM have mechanical strength, batter torque density and high flux linkage is a suitable candidate for electrical vehicle (EV). The major disadvantage of this design are high cogging torque and torque ripple while keeping constant average torque. Four various techniques are applied to minimalize the cogging torque of PMFSM to design it more suitable for PHEV applications. The legitimacy of these techniques has been observed by 3-D and 2-D simulations. Among all techniques the optimal result of Hybrid_C2 technique which reduces the cogging torque 66.28% with 0.7% loss in average torque.
