本文提出了一种新型轮毂电机，巧妙地将磁力齿轮集成到永磁无刷（PMBL）直流电机中，使它们可以共享公共永磁转子，从而提供高效率和高功率密度。而且，可以同时实现直接驱动的低速要求和紧凑型电机设计的高速要求。设计并分析了 2 kW 600/ 4400 rpm 磁力齿轮外转子 PMBL 直流电机，该电机特别适用于电池供电的电动摩托车。
This paper proposes a novel in-wheel motor, which artfully integrates a magnetic gear into a permanent-magnet brushless (PMBL) DC motor so that they can share a common PM rotor, hence offering both high efficiency and high power density. Moreover, the low-speed requirement for direct driving and the high-speed requirement for compact motor design can be achieved simultaneously. A 2-kW 600/ 4400-rpm magnetic-geared outer-rotor PMBL DC motor is designed and analyzed, which is particularly suitable for battery-powered electric motorcycles.
