In this paper a simple dynamic circuit-based model for a rotor surface mounted PMSM with inter-turn winding short-circuit fault is presented. Finite element analysis is used for parameter determination and study the PMSM under fault conditions. The Analytical expressions are proposed for determining the fault model parameters. The proposed circuit model and parameter expressions are validated by time...
We performed a time-stepping finite-element-method (FEM) analysis to study a rotor surface-mounted permanent-magnet synchronous machine with insulation failure inter-turn fault. We used FEM for magnetic field study and determining the machine parameters under various fault conditions. We studied the effect of machine pole number and number of faulted turns on machine parameters. Finally, we used the...
In this paper a simple dynamic model for a rotor surface mounted PMSM with inter-turn winding fault is derived using the reference frame theory. Finite element analysis is used for parameter determination and study of pole number influence. The proposed model is validated by time stepping FEM analysis. The dynamic model results exhibit the same trend as predicted by FEM analysis for different fault...
