Research on flux reversal machine is taking importance day by day because of its unique characteristics. This research through light over different performance of flux reversal machine like three-phase flux linkage, cogging torque, back EMF, average torque, self, and mutual inductance. Moreover, average torque vs stack length and torque ripple is analyzed at different rotor pole and noticed a tremendous shift in performance with changing the number of magnet pairs per pole and observed that two-pairs (4-PM) of PM per pole gives the best result then a pair (2-PM) of PM per pole. All the analysis is done under the same condition, parameters, and materials. As a result, it is concluded that 10-pole model gives higher torque density and better average torque, but with high spicks then 11,13 and 17-pole model. In terms of average torque, the 10-pole model is dominant overall with 3.30Nm (17.097%) higher than 13-pole model, followed by 11-pole model with average torque value of 2.656Nm, while the 17-pole model produce the lowest average torque but spike less. At the end average torque is briefly discussed with respect to current density and stack length.
