Abstract: A method for detecting an anomaly in an induction machine includes obtaining or receiving a signal from the induction machine; processing the signal so as to obtain a low frequency signal, then rectifying the low frequency signal; and, declaring if the anomaly is present, based on the rectified low frequency signal. A system for detecting anomalies is also disclosed. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.
