Study on the stator faults in the field-oriented control of asynchronous machine

Abstract

It is well known that the induction machine is considered by its qualities of robustness and low cost of construction, it happens nevertheless that this one presents an electric or mechanical breakdown.Among these breakdowns, we quote turn-to turn short circuit, stator phase breakdown, rotor bars breakdownwn… etc. In our article, we are interested in the study by simulation of the operation of an asynchronous machine presenting an electric breakdown which is the broke stator phase by modeling the machine in the two-phases reference mark. Another point is discussed in this article, it relates to the influence of this fault on the vector control. The results obtained are presented at the end of the article.
