According to the driving motor magnetic suspension technology in the multi-rotor unmanned aerial vehicle power system disclosed by the invention, lift force generated in the rotors of the unmanned aerial vehicle is transmitted to the unmanned aerial vehicle body in the form of magnetic suspension force instead of being transmitted through a motor bearing, so that friction force and friction loss in the bearing are eliminated, and the driving efficiency of the motor is improved; and the magnetic suspension force and the lift force are infinitely balanced without a controller, so that the manufacturing cost is equivalent to that of a traditional non-magnetic suspension motor, and the manufacturing is relatively easy.
本发明披露的多旋翼无人机动力系统中的驱动电机磁悬浮技术,使无人机旋翼中所产生的升力以磁悬浮力的形式传递到无人机体,不再通过电机轴承传递力,从而消除了轴承中的摩擦力和摩擦损耗,提高了电机的驱动效率,且磁悬浮力与升力随遇平衡,无需控制器,因此其制造成本与传统非磁悬浮电机相当,制造也相对容易。
