Abstract
PurposeThe purpose of this paper is to present a new model to study inter‐turn short circuit faults in a permanent magnet synchronous machine.Design/methodology/approachThe machine is modeled by using classical two‐axis theory, and the equations are modified to take into account the stator inter‐turn faults. A state space form of the system is presented for dynamic simulations.FindingsThe machine model is global and can work in both normal and fault conditions due to a fictitious resistance in the winding circuit. Various simulation results have been presented indicating the fault instant and its corresponding effect. Validation is carried out by transient time finite element simulations.Originality/valueThe model can serve as a step towards development of fault detection and diagnosis algorithms.
