Mechanical imbalances and bearing faults account for a large majority of the faults in a
machine, particularly for small-medium size machines. Therefore, their diagnosis is an …

This paper proposes a new approach to use stator current and efficiency of induction motors
as indicators of rolling-bearing faults. After a presentation of the state of the art about …

In this paper, the effects of inverter harmonics on motor current fault signatures are studied in
detail. It is theoretically and experimentally shown that the fault signatures caused by the …

Early diagnosis of faults in induction machines is an extensively investigated field, for cost
and maintenance savings. Mechanical imbalances and bearing faults account for a large …

The book covers various issues related to machinery condition monitoring, signal
processing and conditioning, instrumentation and measurements, faults for induction motors …

Nowadays, many industrial applications require online systems that combine several
processing techniques in order to offer solutions to complex problems as the case of …

Due to the importance of induction motors' continuous operation, early detection of faults has
become a major trend. As reported in an IEEE study, bearing failures include more than half …

In this paper, we present the results of an ongoing investigation relating to the detection of
static and dynamic eccentricity in cage induction motors fed by a pulsewidth-modulation …

A considerable amount of papers has been published in recent years proposing supervised
classifiers to diagnose the health of a machine. The usual procedure with these classifiers is …

Condition monitoring of bearings is an open issue. The use of the stator current to monitor
induction motors has been validated as a very advantageous and practical way to detect …
