Abstract
This paper proposes magnetostatic analysis of Switched Reluctance Motor (SRM) under angular misalignment fault to evaluate the performance of the motor under different operating conditions. In this analysis three-dimensional finite element method (FEM) is used to simulate reliable and precise model by considering the complex motor magnetic geometry, end effects, axial fringing effects as well as nonlinear properties of the magnetic materials. The FE analysis is performed to obtain the static magnetic characteristics of SRM including flux density, flux linkages, terminal inductance and mutual inductance profile under different rotor positions for different varying degree of faults. Consequently, it presents assessing the features of mutual inductance in inactive phases to study the variations of diagnosis index. The results obtained present useful information regarding the detection of fault and its direction as well as the amount of angular misalignment fault in the motor. To the best knowledge of the authors, such an analysis has not been carried out previously.
