The unmanned aerial vehicle single-motor coaxial power system comprises a motor, and a steel shaft capable of rotating along with a rotor of the motor is arranged on the motor; an upper paddle seat mechanism for fixing the upper paddle is arranged at the upper end of the steel shaft; a lower paddle seat assembly is mounted at the lower end of the upper paddle seat mechanism on the steel shaft; the lower paddle seat assembly comprises a transmission mechanism and a lower paddle seat mechanism used for fixing a lower paddle, the transmission mechanism is installed on the upper end face of a rotor of the motor, the lower paddle seat mechanism is rotatably connected with the steel shaft, and when the rotor of the motor rotates, the lower paddle seat mechanism is driven by the transmission mechanism to rotate around the steel shaft. The upper paddle and the lower paddle are consistent in rotating speed and opposite in rotating direction, single-motor direct-drive coaxial is achieved, and compared with non-direct-drive output coaxial, the size is smaller, and the weight is lighter; and compared with a single paddle, the pulling force is improved, the operability is better, the linearity of the model plane is better, and the energy consumption is lower.
本发明公开了一种无人机单电机共轴动力系统,包括电机,所述电机上设置有可跟随电机的转子转动的钢轴;所述钢轴上端设置有用于固定上桨叶的上桨座机构;所述钢轴上位于所述上桨座机构的下端安装有下桨座组件;所述下桨座组件包括传动机构和用于固定下桨叶的下桨座机构,所述传动机构安装在电机的转子的上端面,所述下桨座机构与钢轴可转动连接,所述电机的转子转动时通过传动机构带动下桨座机构绕着钢轴转动。本发明的上下桨叶转速一致,旋转方向相对,实现了单电机直驱共轴,相对于非直驱输出共轴,体积更小,重量更轻;相对于单桨叶提升了拉力,可操作性更好,使模型飞机直线性更好,耗能更低。
