This paper presents a theoretical approach as far as faulty permanent magnet synchronous machines (PMSM) are concerned. The knowledge of PMSM's behavior under inter-turn fault is very useful in order to check drive performances under fault conditions. Control, stability and fault detection often require models related to electrical or mechanical faults. The aim of this paper is to develop a dynamic model of a PMSM under fault conditions without using circuit models coupled with finite element analysis (FEA). The method exposed in this paper only needs some preliminary FE computations that can be used in order to include winding distributions and leakage fluxes in the slots.
