In this study, the performance of a triple redundant nine‐phase permanent magnet‐assisted synchronous reluctance motor with delta‐connected windings is comprehensively assessed and compared with that of wye‐connected winding under healthy and fault conditions, including open circuit, inter‐turn short‐circuit and terminal short circuit. The steady‐state torque behaviour, loss, efficiency and temperature distribution of the two winding configurations are analysed and compared. It is shown that the delta‐connected winding has higher output torque under one phase open‐circuit fault and lower inter‐turn short‐circuit current with three‐phase terminal short circuit.
