This paper presents some analysis techniques of the voltages induced in the stator windings after supply disconnection, to detect broken rotor bars in induction motor (IM). When the motor is disconnected from the supply voltage, the broken bars cause a distortion of the magnetomotive force generated by rotor windings, and some particular harmonics induced(More)
Due to its many advantages, the switched reluctance machine (SRM) finds several applications such as in the high-speed motor operation or in the power generation. However, unlike many other electric machines, the SRM has the particularity of working in highly saturated regime, which leads to a nonlinear mathematical model. Therefore, this nonlinear behavior(More)
This paper presents an analysis of effects of dynamic air-gap eccentricity on the performances of a 6/4 Switched Reluctance Machine (SRM) through finite element analysis (FEA) based on a FEMM package associated to MATLAB/SIMULINK package software. Among the various Time-Frequency methods used for detection of defects, the Time-Frequency Representation (TFR)(More)
In the case of one phase failure, the switched reluctance motor (SRM) will behave nearly the same, both in open circuit and in short circuit failure. This means, that the machine will understand the two faults in the same way which makes the SRM faults detection and diagnosis a more challenging task. In this paper, a diagnosis method based on statistical(More)
