N2 - A four-phase fault-tolerant permanent-magnet (PM) machine is designed for aerospace application. The causes of PM loss and torque ripple are analyzed under the condition of adopting fractional slot concentrated winding (FSCW) and surface-mounted PM structure. Then the Quasi-Halbach PM structure is introduced to reduce the PM loss and torque ripple. Furthermore, the machine performances are improved by optimizing the PM thickness, magnetization angle, rotor core thickness and slot-opening width. Besides, performances of the proposed machine under different open-circuit faults are analyzed, and corresponding open-circuit fault-tolerant control strategies with zero sequence current taken into consideration are investigated.
