—In this paper the incipient fault detection problem in induction machine stator-winding is considered. The problem is solved using a new technique of change point detection in time series, based on a three-step formulation. The technique can detect up to two change points in the time series. The first step consists of a Kohonen neural network(More)
Although nowadays ac drives are more frequently used, dc drives continue being used, mainly in industrial plants, as in Açominas. Normally, duals converters compose these drives, were faults related with them are important in relation with available time of equipments. Besides, speed sensors, as taco generator and pulse generator, are important factor to(More)
