The influence of the presence of errors in the behavior of a switched reluctance motor is investigated in this paper. The dynamic response of a Switched Reluctance Motor (SRM) is analyzed by the coupled structural and electromagnetic Finite Element Method (FEM). The dynamic behavior of the motor under failure operation can lead us to non-invasive diagnosis of faults and rotor eccentricity in switched reluctance machines by monitoring the dynamic response of the system (Torque and Speed).
