The invention belongs to the technical field of propellers, and particularly relates to an electric water-air dual-purpose propeller. The propeller comprises an outer rotor motor, a rim motor, a propeller body, a stator support, a one-way clutch mechanism and a propeller mounting frame, the outer rotor motor is connected with the propeller mounting frame through the stator support, an output shaftof the outer rotor motor is connected with the propeller body, and the rim motor is arranged on the outer side of the propeller body in a sleeving mode and connected with the propeller body through the one-way clutch mechanism; when the electric water-air dual-purpose propeller works in air, the outer rotor motor drives the propeller body to rotate, and the one-way clutch mechanism is separated from the propeller body; when the electric water-air dual-purpose propeller works in water, the rim motor drives the propeller body to rotate, and the one-way clutch mechanism is meshed with the propeller body. By means of the characteristics of high rotating speed and low torque of the outer rotor motor and the characteristics of low rotating speed and high torque of the rim motor, underwater andaerial efficient propulsion is achieved, and the characteristics of compact structure, high propulsion efficiency and the like are achieved.

    本发明属于推进器技术领域,特别涉及一种电动水空两用推进器。包括外转子电机、轮缘电机、螺旋桨、定子支架、单向离合机构及推进器安装架,其中外转子电机通过定子支架与推进器安装架连接,外转子电机的输出轴与螺旋桨连接,轮缘电机套设于螺旋桨的外侧、且通过单向离合机构与螺旋桨连接;当在空气中工作时,外转子电机驱动螺旋桨转动,单向离合机构与螺旋桨脱离;当在水中工作时,轮缘电机驱动螺旋桨转动,单向离合机构与螺旋桨啮合。本发明利用了外转子电机高转速、低扭矩和轮缘电机低转速、高扭矩的特性,实现水下和空中的高效推进,具有结构紧凑、推进效率高等特点。
