N2 - Permanent magnet synchronous motors (PMSMs) are widely used in the aerospace field due to the high power density, high torque density, and high efficiency. Due to the excellent flux-focusing performance, PMs in Halbach array can significantly increase the peak fundamental air-gap flux density of PMSMs and hence, a better torque capacity. In this article, 8-pole 9-slot motors with various PM configurations are compared in terms of optimization methods, magnetic flux density, open-circuit electromotive force, and on-load torque by finite element analysis (FEA). The results show that the machine in Halbach array with 45 ° magnetization has significant flux-focusing capability, which can effectively improve the torque density. Moreover, the machine in Halbach array with 45 ° magnetization exhibits the smallest PM eddy current loss and hence, a higher efficiency.
