The invention discloses an unmanned helicopter and a main rotor driving method thereof.The unmanned helicopter comprises a fuselage, a main rotor and a first power device providing power for the main rotor, and the first power device comprises two motors, two electronic speed regulators, a speed reducer and a synchronous belt; power output parts of the two motors are connected with a power input part of the speed reducer through the synchronous belt, a power output part of the speed reducer is connected with a transmission shaft of the main rotor, and the two electronic speed regulators are correspondingly and electrically connected with the two motors; the machine body is provided with a first liquid cooling system connected with the two electronic speed regulators through liquid paths and a second liquid cooling system connected with the two motors through liquid paths. The main rotor driving method comprises the steps that one electronic speed regulator works in a rotating speed negative feedback closed-loop control mode, and the other electronic speed regulator works in a rotating speed open-loop control mode. According to the invention, the large-load unmanned helicopter can be realized at low cost, thermal crosstalk can be avoided, and speed interference between the two motors can be reduced.

    本发明公开了一种无人直升机及其主旋翼驱动方法,本无人机包括:机身,主旋翼,向主旋翼提供动力的第一动力装置,第一动力装置包括两个电动机、两个电子调速器、减速器以及同步带,同步带将两个电动机的动力输出部与减速器的动力输入部相连,减速器的动力输出部与主旋翼的传动轴相连,两个电子调速器与两个电动机对应电连接;机身配置有与两个电子调速器液路相连的第一液冷系统,以及与两个电动机液路相连的第二液冷系统。本主旋翼驱动方法包括:将一个电子调速器工作于转速负反馈闭环控制模式,而且另一个电子调速器工作于转速开环控制模式。本发明能够低成本地实现大载荷的无人直升机,还可以避免热串扰,可以减少两个电动机之间的速度干涉。
