Abstract :
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.
