The framework is intended for fine-tuning initial optimum designs to further improve the steady-state torque quality of LSPMSMs. The proposed framework was successfully implemented on an LS-PMSM design. A notable decrease in steady-state torque ripple was achieved without a significant reduction in steady-state performance and transient load synchronization capability. It has been shown that the proposed robust torque ripple mitigation framework is both functional and time efficient and can be applied to a wide range of electrical machinesenLine startPermanent magnet synchronous machinesTorque rippleRobust designOptimizationTaguchi methodFinite element analysisPresentation
