Abstract

In this paper, a novel magnetic parameter design methodology is proposed for switched reluctance motors (SRMs). Based on the nonlinear characteristic of flux linkage, the design equations of structural and winding parameters are derived. The benefit is that there are no meaningless empirical design coefficients in the proposed design methodology. Three SRMs with multiple phases, i.e., 12/8, 10/8, and 18/20 stator/rotor poles SRMs, are initially designed according to the derived equations. Then, multiobjective optimization is carried out to realize the design objectives of output torque, current density, and torque ripple. The design solutions of the three SRMs with similar current density and slot fill factor are selected from the Pareto front, respectively, and the performance comparisons are conducted. The proposed design methodology is verified by the selected optimal solutions after the substitution into the design equations. Finally, the designed SRMs are prototyped and tested to validate the simulation results and further verify the effectiveness of the proposed design methodology.
