In this paper, a dynamic model for PMSM with inter-turn fault is presented. FEM analysis is used for study the PMSM with inter-turn fault. Two methods for analytical calculation of parameters are presented. The first method widely used in literature computes the faulty inductances by applying a simple percentage on the parameters of healthy machine. The analytical expressions are established for determining...
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 PMSM with inter-turn winding fault is derived. FEM is used for parameter determination of the machine with inter-turn fault. This fault model is used to study the behavior of the machine with inter-turn fault. The experimental test is conducted to validate the fault model for different levels of fault severity. The comparison of the results obtained by the...
