A MATLAB tool is developed for finite element and adjoint sensitivity analyses of switched reluctance motors (SRMs). The tool solves for magnetic vector potential throughout the SRM domain taking nonlinearity of magnetic materials into consideration. It then calculates electromagnetic torque, flux density, air region stored energy, and flux linkage at different rotor positions. The tool exploits structural mapping technique to control 8 geometric design parameters of SRMs. These parameters are yoke thickness, teeth height, teeth pole arc angle, and teeth taper angle of both stator and rotor. The tool also evaluates the desired sensitivities with respect to these geometric design parameters in addition to the number of turns per phase.
