Abstract
The present paper focuses by means of an experimental study, on the effect of a bearing fault on the stator current signatures in induction motors. The variation in the amplitude of the characteristic components is not so significant. For that and in order to depict the presence of the fault harmonic signatures, the authors used the phase analysis of Hilbert transform applied on the spectrum modulus of the line current.
