The synchronous reluctance motor (SynRM) is gaining attention in various industrial applications due to its high efficiency and rugged rotor structure. This paper presents a comparative study of the performance of SynRM when driven by sine wave and square wave signals. The analysis covers key performance metrics including efficiency, power factor, torque ripple, noise, etc. The study summarizes the advantages and disadvantages of each driving method. And the findings provide insights for selecting the appropriate driving method for SynRMs in different application scenarios, balancing performance, complexity, and cost.
