Abstract

In this paper, a new hybrid-excited flux switching (HEFS) machine with outer-rotor is proposed, which possesses distinct feature of high fault-tolerant operation. Comparing with the conventional permanent-magnet (PM) machine, it combines the merits of flux switching, low-cost, and high mechanical integrity. Furthermore, its fault-tolerant feature ensures its continuous operation in the event of winding faults. Hence, a new 12/10-pole HEFS machine is designed and implemented. The proposed machine is shown. The outer-rotor is merely a single piece iron, the stator contains 12-slots armature coils, 12-slots field excitation coils (FECs), and 12-pole PMs, where armature coils and FECs are located in alternate way.
