Abstract
This paper deals with the influence of a stator fault, power switch faults and open phase fault conditions on the properties of a five-phase induction machine under open-end stator winding (OeW-FPIM). This paper will develop an accurate mathematical model to simulate the faulty OeW-FPIM drives. The proposed model is based on the theory of electromagnetic coupling of electrical circuits coupled to the differential equation system governing the machine behavior in presence of the stator winding faults. In fact, when a short circuits between coils occurs, the stator winding function of the injured phase changes. As a consequence, the stator resistance, the stator inductance of this phase and its mutual inductance with all the other circuits change also. Consequently, the inductances and resistance matrices will be changed by taking into account the introduced coefficients of short-circuited turns. The performance of the OeW-FPIM drives have been tested via simulation under different fault scenarios conditions.
