Modeling and characterizing the inter-turn short circuit fault in PMSM
2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011In 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 ...
