Design and Analysis of Line-Start Synchronous Reluctance Motor Considering the Maximum Inertia and Power Factor

Abstract

In this paper, the design and analysis of a line-start synchronous reluctance motor (LS-SynRM) are performed considering the maximum inertia and power factor. Because LS-SynRM must be operating the synchronous speed, the synchronization capability of load is important for the various industrial application. The electromagnetic and mechanical transient analysis of a finite element analysis (FEA) are used to analyze the maximum load inertia. Furthermore, because the power factor is also important index in the industrial application according to IEC 60034-1, the bridge design is performed considering the power factor and mechanical stress. The basic model is selected considering the maximum inertia and power factor. Based on the basic model, the optimal design is performed considering the power factor and power factor. Finally, the final model of LS-SynRM is manufactured, and experiment is performed to verify FEA result.
