Synchronous reluctance motors performance based on different electrical steel grades

Recently, the Synchronous Reluctance Motor (SynRM) has received more attention for many applications, thanks to its rugged construction and low cost [1]. Over the past decades, developments in machine design methodology, high quality magnetic materials, and advanced power electronics allow the machine designers to enhance the performance of the SynRM which depends mainly on the direct and quadrature axis inductances (L_d, L_q). Therefore, considerable attention has been given to improve the saliency ratio of the SynRM, taking into account the core material and its saturation behaviour. Several papers have focused on the rotor geometry design and the saturation effect on the performance of the SynRM [2, 3]. However, the effect of the electrical steel grades on the performance of the SynRM has not been deeply studied.
