Abstract
Bearing faults (BFs) are one of the main failure roots for induction motors (IMs) systems. It is necessary to monitor the conditions of IMs during their operation to prevent such failures. Stator current signal obtain by current probes which has advantages of inexpensive, reliable and non-invasive is preferable for condition monitor of IMs. Research focusing on modelling and analysis of stator current signal with defective bearings suggested the characteristic frequency of BFs in current spectrum could be a diagnosis indictor, however, it is difficult to see the characteristic frequency by spectrum analysis. On the other hand, when BFs occurs, it may also cause the non-uniform air gap in IMs, the frequency components related to the non-uniform air gap can be an indirect indictor to detect BFs in IMs. This paper investigated several related frequency components. Based on the experiment results, it was found that the responses at the rotor bar pass frequency (RBPF) component which is obtained by a modulation signal bispectrum sideband (MSB-SE) method and eccentricity frequency (EF) components in low frequency range are more sensitive to bearing fault conditions and could be used as sensitive diagnosis indictors.
