The embodiment of the invention relates to the technical field of motors, and particularly discloses a motor and an unmanned aerial vehicle. The motor comprises a rotor assembly and a stator assembly. The rotor assembly comprises a rotor support and a rotating shaft body, the rotor support comprises a fixing part, connecting parts and a support part, the support part is arranged on the outer side of the fixing part, the multiple connecting parts are arranged at intervals, a first included angle exists between every two connecting parts, and the connecting parts are connected between the fixing part and the support part and provided with vibration reduction grooves. The stator assembly comprises a stator base, a fixed bearing and a rotating bearing, the stator base is installed on the rotating bearing, the fixing part and the fixed bearing clamp and fix the rotating bearing, the rotating bearing is installed on the rotating shaft body, and a gap exists between the stator base and the support part. Through the above structure, the first included angle exists between the connecting parts, and the vibration reduction grooves are arranged, so that the vibration frequency of the electromagnetic excitation force and the vibration frequency of the rotor assembly are staggered, thereby weakening the coupling resonance of the electromagnetism and the structure, and protecting the motor.
本申请实施例涉及电机技术领域,尤其公开了一种电机及无人机,包括。电机包括转子组件和定子组件。转子组件包括转子支架和转轴本体,转子支架包括固定部、连接部和支架部,支架部设置于固定部外侧,多个连接部间隔设置,两连接部之间存在第一夹角,连接部连接于固定部和支架部之间且设有减振凹槽。定子组件包括定子座、固定轴承和转动轴承,定子座安装于转动轴承,固定部和固定轴承夹持固定转动轴承,转动轴承安装于转轴本体,定子座与支架部之间存在间隙。通过上述结构,每一连接部之间存在第一夹角,且设置有减振凹槽,以使电磁激振力的振动频率与转子组件的振动频率错开,从而减弱电磁与结构的耦合共振,保护电机。
