| Abstract |
In this paper, the operating points of a line-start synchronous reluctance motor (LS-SynRM) are analyzed based on the mathematical model, and the performances such as efficiency and power factor are analyzed using a finite element analysis (FEA). Based on the mathematic model of LS-SynRM, the operating points is analyzed according to the dq-axis inductance. The design parameters that determine the dq-axis inductance and phase resistance are selected as a turn per slot, a stack length, and that determine a barrier design. Using a finite element analysis (FEA), the operating points are analyzed according to the design parameters. Furthermore, the performances of LS-SynRM according to the operating points are analyzed to consider the efficiency and power factor. The performance maps according to three design parameters are analyzed to optimize the efficiency and power factor. To verify FEA result, final LS-SynRM is manufactured and the experiment is performed. |
