Outer rotor motor, fan component and air conditioner

The external rotor motor comprises a rotor assembly, a stator assembly and a first buffer member, the rotor assembly comprises a housing and a rotating shaft, a first excitation member is arranged in the housing, the rotating shaft is arranged in the housing and rotates synchronously with the housing, and the first excitation member is arranged in the housing. The shell is provided with an opening, the stator assembly comprises an end cover and a second excitation part arranged on the end cover, the end cover covers the opening in a sealing mode, the second excitation part is sleeved with the first excitation part, a center hole is formed in the second excitation part, a matched bearing is arranged between the rotating shaft and the center hole, and the first excitation part and the second excitation part are matched with each other. The first buffer piece is arranged between the shell and the end cover, and the first buffer piece is constructed to be compressible and deformable. According to the external rotor motor provided by the utility model, the impact between the shell and the end cover can be reduced, and the impact force borne by the matched bearing is further reduced.
