【 摘 要 】

In this study we investigate the possibility of broken bar fault detection in an induction machine rotor using spectral analysis of the stator currents. The numerical method, presented in this work, based on the Hilbert transform shows the possibility of improving the detection of faults in electrical machines. The results obtained using this method are validated experimentally on a test bench with an induction motor of 5.5 kW.
