A novel permanent magnet block external efficient rotor propeller of an unmanned aerial vehicle and a manned aerial vehicle is characterized in that a permanent magnet block is externally arranged on a rotor structure, magnetic field distribution is optimized, and the thrust and efficiency of the propeller are remarkably improved. According to the design of the propeller, the newest policy of low-altitude airspace management is fully considered, and the national requirement for low-altitude economic high-quality development is met. The propeller is expected to become a key component for promoting the progress of the low-altitude industry and assists in realizing optimal utilization of airspace resources. The design is as shown in figure (figure 1), a stator is an outer ring, a plurality of groups of S-pole and N-pole winding coils are oppositely arranged on the inner side of the stator, and a rotating magnetic field is generated after the stator is electrified. The design of the rotor is shown in figure (figure 2), the rotor is an inner ring, a plurality of groups of S-stage and N-stage permanent magnets are oppositely mounted on the outer side of the rotor, the center of the rotor is the center of the propeller instead of a shaft, and the shaft is located at the position, generating a rotating magnetic field, of the outer side of the rotor and the inner side of the stator. A fixing piece is arranged in the center of the rotor and used for fixing and connecting propeller blades.

    一种新型无人机和有人机永磁块外置高效转子螺旋桨,其核心在于将永磁块外置于转子结构,优化磁场分布,显著提升螺旋桨的推力和效率。该螺旋桨设计充分考虑了低空空域管理的最新政策,符合国家对低空经济高质量发展的要求。该螺旋桨有望成为推动低空产业进步的关键部件,助力实现空域资源的优化利用。其设计如图(图1)所示,定子为外圈,在定子内侧对置安装数组S级和N级绕组线圈,通电后产生旋转磁场。转子设计如图(图2)所示,转子为内圈,在转子外侧对置安装数组S级和N级的永磁体,转子中心即为螺旋桨的中心,这里不是轴,轴位于转子外侧与定子内侧产生旋转磁场的位置。在转子中心设置固定件,用来固定和连接螺旋桨叶片。
