Abstract

Synchronous Reluctance Machines (SynRMs) have gained considerable attention for their high-performance capabilities and simplicity. However, these machines can be prone to high torque ripple if not designed precisely. This paper conducts an analysis of the rotor geometry impact on the performance of SynRMs for electric vehicles applications. A rotor structure with three-flux barriers per pole is optimized using a Multi-Objective Genetic Algorithm and Finite Element Method. The optimization was carried out for two different rotor configurations: one with symmetric flux barriers and the other with asymmetric ones. The assessment of different performance indicators was conducted at different operating points, showing the benefits of the asymmetric version with respect to the symmetric one. The results of this study provide valuable insights for the design of SynRMs with improved performance and reduced torque ripple.
