Zusammenfassung:The paper focuses on the fault detection of a five-phase permanent-magnet (PM) machine. This machine has been designed for fault tolerant applications, and it is characterised by a mutual inductance equal to zero and a high self inductance, with the purpose to limit the short circuit current. The effects of a limited number of short-circuited turns were investigated by theoretical and finite element (FE) analysis, and then a procedure for fault detection has been proposed, focusing on the severity of the fault (i.e. the number of short-circuited turns and the related current).
