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...
A time stepping FEM is performed for study of PM motor with inter-turn fault. The novel analytical expressions are proposed for calculation of faulty machine inductances from healthy machine parameters. The proposed expressions are validated by FEM and can be used in the circuit based fault models. Finally, the FEM is applied for studying the PM machine under various fault conditions.
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...
A limited short circuit current PM motor is studied based on the segmentation of the rotor magnets. The principle is to reduce the magnetic flux by means of magnets subdivision and an increase of rotor pole number. The effect of magnet segmentation on machine characteristics is analyzed using finite element method (FEM). The short circuit current of designed fault tolerant machine is well limited...
A time stepping FEM analysis is performed for fault study of PM motor with inter-turn fault. FEM is used for magnetic field study and identification of the machine parameters. Novel analytical expressions are presented and validated for calculation of inductances based on field calculation. Finally, the developed fault model is used to study the PM machine behavior under different fault conditions.
In the context of more electric aircrafts, the use of electric actuators instead of hydraulic ones is one of the main topics of research and development in electrical engineering. A high level of reliability, the redundancy and the compactness are required for aircraft electrical actuators. For achieving these purposes the classical solution consists in using two identical actuators motorized each...
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...
In this paper a simple dynamic model for induction machines (IM) with inter-turn winding fault is established. Finite element method is used for parameter identification of the machine under fault condition. The proposed dynamic model is validated by time stepping finite element (FE) analysis. The dynamic model results exhibit the same trend as predicted by FE analysis for different fault insulation...
