On the Electromagnetic Steel Selections and Performance Impact Assessments of Synchronous Reluctance Motors

To achieve relatively lower costs and higher operational efficiencies, without adopting permanent magnets or rotor conductors, the synchronous reluctance motor (SynRM) has received more and more attentions as a competitive solution recently. To establish a rational guidance for the related designs and constructions, this paper is aimed to present the thorough performance impact assessments of SynRMs that are composed of different electromagnetic steels at various operational specifications. Based on the magnetization and hysteresis characteristics of the steel sheets, variations of the average torques, torque ripples, and iron losses by using different stator and rotor materials are investigated, and some valuable comparison results can be provided for designers and engineers in the related motor and metal industries.
