Investigations of algorithms for bearing fault detection in induction drives

This paper presents signal methods dedicated to the fault detection in the mechanical part of an induction drive: bearing damage, eccentricity and rotor unbalance. An experimental bench test is described and used to create and characterise these faults. Two methods for bearing faults detection are also detailed: the cepstrum and an original method (parcels summation method). These algorithms are tested on synthetical and real signals.
