“…In [9], two dimensional Finite Element (2D-FE) coupled with quasi Newton-Raphson method are used to analyze dynamic eccentricity. It declared that the field distribution and torque in faulty motor can be less or more than healthy motor, which depend on the rotor position and the currents exciting of the stator phases.…”

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.

The paper describes indirectly coupling timestepping techniques using quasi Newton-Raphson solvers and on-line field calculations. Due to the quasi Newton-Raphson solvers the electric and magnetic subsystems are strongly coupled and the number of independent currents exciting the magnetic field is not limited. Compared to indirectly coupling timestepping techniques using state-space models and on-line field calculations, the number of field calculations can be reduced significantly. As a first test, these indirectly coupling time-stepping techniques are used to simulate the dynamic response of a ringcore transformer. The simulation results are in good accordance with the measurements.
