Rotor Design for Improving the Maximum Inertia and Power Factor in Line-Start Synchronous Reluctance Motor

초록

In this paper, the design and analysis of a line-start synchronous reluctance motor (LS-SynRM) is performed considering the maximum inertia and power factor. Because LS-SynRM must be operating the synchronous speed, the capability of load synchronization is important for the various industrial application. The electromagnetic and mechanical transient analysis of a finite element analysis (FEA) is 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. Based on the basic model, the optimal design is performed to improve the power factor. The design parameters, constraints, and objective functions are considered to optimization of LS-SynRM. Finally, the optimal model of LS-SynRM is manufactured, and experiment is performed to verify FEA result.
