The invention discloses a multi-rotor brushless motor. The motor comprises two mounting base plates, a first bottom plate is fixed to the tops of the two mounting base plates, first baffles are fixedto the positions, close to the edges of the two sides, of the top of the first bottom plate, second baffles are fixed to the tops of the two first baffles, and a second bottom plate is fixed between the tops of the two second baffles. In the present invention, due to a fact that two (or more) brushless motors are each composed of a first stator, a first rotor, a second stator and a second rotor, the heat dissipation efficiency is better; therefore, the brushless motor on the unmanned aerial vehicle can operate in a high-rotating-speed interval for a long time; due to the fact that large powerredundancy is reserved in the design of the unmanned aerial vehicle, when one set of rotors or stators of the multi-rotor motor break down, the other set of rotors and stators can still operate in a short time, safe landing or return voyage can be achieved in emergency, and the probability of crash accidents is reduced.

    本发明公开了多转子无刷电机,包括安装基板,所述安装基板共设置有两个,且两个安装基板的顶部固定有第一底板,所述第一底板的顶部靠近两侧边缘处均固定有第一挡板,两个所述第一挡板的顶部均固定有第二挡板,两个所述第二挡板的顶部之间固定有第二底板。本发明中,由于两个(或多个)无刷电机,分别由第一定子和第一转子与第二定子和第二转子部分组成,其拥有更优的散热效率,因此无人机上的无刷电机可以长时间运行在高转速区间,由于无人机在设计是有预留很大的动力冗余,所以当该多转子电机某一组转子或定子出现故障是,另一组转子和定子仍可以短时间运行,可以在紧急情况下的安全降落或返航,降低坠机事故概率。
