Space vector harmonic analysis of a five-phase PM motor including asymmetries

This paper deals with the harmonic analysis of the orthogonal space vector components of a five-phase machine. It gives a complete analysis of the harmonic contents of the resulting space vector, considering both symmetric and asymmetric systems. Then, the impact of some phase asymmetries on the space vector harmonic contents is investigated. Therefore the results achieved in such a study will be of reference for determining a fault diagnosis procedure.
