The invention provides an electric coaxial dual-rotor integrated driving device, and relates to the technical field of aircraft design and manufacturing. The device comprises a coaxial contra-rotating permanent magnet synchronous motor, a motor driving module used for driving the coaxial contra-rotating permanent magnet synchronous motor to operate and two sets of paddles installed on output shafts of the coaxial contra-rotating permanent magnet synchronous motor, the coaxial contra-rotating permanent magnet synchronous motor is provided with two output shafts on the same side, and the two output shafts are arranged in a sleeved mode. The rotation directions of the two output shafts are opposite, and the two sets of paddles are installed on the two output shafts respectively. The device is large in power volume ratio, high in power density, simple in structure, easy and convenient to control, capable of effectively improving the effective load of the electric multi-rotor unmanned aerial vehicle, high in reliability and easy to implement. The multi-rotor unmanned aerial vehicle is simple in structure, high in integration level and capable of self-balancing reaction torque, so that the multi-rotor unmanned aerial vehicle can be matched with a single set or multiple sets of coaxial double-rotor power devices, and the overall structural layout is more convenient.

    本申请提供了一种电动共轴双旋翼集成驱动装置,涉及航空器设计制造技术领域,所述装置包括共轴对转永磁同步电机、用于驱动所述共轴对转永磁同步电机运转的电机驱动模块以及安装在所述共轴对转永磁同步电机的输出轴上的两组桨叶,所述共轴对转永磁同步电机设有两个同侧的输出轴,两个输出轴间套设,两个输出轴的旋转方向相反,所述两组桨叶分别安装在两个输出轴上。该装置功率体积比大,功率密度高,结构简单,控制简便,能够有效提升电动多旋翼无人机的有效载荷,可靠性高且易于实现。因为自身结构简单集成度高,且能自平衡反扭矩,多旋翼无人机可以匹配单套或者多套共轴双旋翼动力装置,总体结构布局更方便。
