Fault diagnosis of electric motors is still a challenging task for researchers. Various rotor cage faults detection techniques for electric motors have been proposed during the last two decades. One of these techniques widely used is the one based on the stator current spectral analysis which is still an open topic of research. This paper focusses on this technique; which has proven to be simple and...
We present in this paper an overview of the slot harmonic frequency detection applied to the broken rotor bars faults diagnosis This technique uses the behavior of the current spectral analysis and the estimation of the rotor slot harmonic to detect broken rotor bars in three phase induction machine. Experimental tests performed with broken rotor bars show the effectiveness and merits of the proposed...
