The invention relates to the technical field of unmanned aerial vehicles, and discloses an intelligent efficient electric constant-speed variable-pitch propeller system which comprises a brushless motor and a motor fixing seat, the brushless motor is fixedly connected with one side of the motor fixing seat, a center shaft of the brushless motor is of a hollow structure and is provided with a variable-pitch rod in a penetrating mode, and a variable-pitch three-blade part and a variable-pitch rod driving assembly are arranged at the two ends of the variable-pitch rod respectively. The propeller angle can be automatically adjusted under different flight speeds, it is guaranteed that the propeller operates in the highest efficiency state all the time, the economical efficiency is improved, the efficiency of a traditional unmanned aerial vehicle propeller is improved, and the technical threshold of an electric constant-speed variable-pitch propeller is lowered, so that small and medium-sized unmanned aerial vehicles can also carry the efficient and economical electric constant-speed variable-pitch propeller system, and the overall flight performance is improved.

    本发明涉及无人机技术领域,公开了一种智能高效电动恒速变距螺旋桨系统,包括无刷电机和电机固定座,所述无刷电机与电机固定座的一侧固定连接,所述无刷电机的中心轴为中空结构,且穿设有变距杆,所述变距杆的两端分别设置有变距三桨叶部件和变距杆驱动组件。本发明可以在不同飞行速度情况下自动调节桨叶角功能,保证螺旋桨始终处于最高效率状态运行,提高经济性,提高传统无人机螺旋桨效率,降低电动恒速变距螺旋桨技术门槛,使得中小型无人机同样可以搭载高效经济的电动恒速变距螺旋桨系统,提高整体飞行性能。
