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 an inner ring part, a first buffer part and an outer ring part, the first buffer part comprises a first buffer ring and a first connecting part which are elastic, the first connecting part is connected between the inner ring part and the first buffer ring at intervals, and the first buffer ring is arranged around the inner ring part; the outer ring part is arranged around the first buffer ring. The stator assembly comprises a stator base, a fixed bearing and a rotating bearing, the stator base is installed on the side, away from the rotating shaft body, of the rotating bearing, a gap exists between the stator base and the rotor support, the inner ring part and the fixed bearing clamp and fix the rotating bearing, and the rotating bearing is installed on the rotating shaft body. Through the structure, the first buffer ring and the first connecting part have elasticity to buffer electromagnetic exciting force and structural vibration, coupling resonance of electromagnetism and the structure is weakened, and the motor is protected.
