The invention discloses a bearing assembly which comprises a rotor shaft, a radial sliding bearing and a single-row deep groove ball bearing. The rotor shaft penetrates through the stator, and the two ends of the rotor shaft are arranged on the first limiting assembly and the second limiting assembly respectively. The radial sliding bearing is located at one end of the stator and arranged in the first limiting assembly of the rotor shaft in a penetrating mode. The single-row deep groove ball bearing is located at the other end of the stator and arranged in the second limiting assembly of the rotor shaft in a penetrating mode. According to the scheme, by adopting the combined structure of the radial sliding bearing and the single-row deep groove ball bearing, the radial position and stress of the rotor of the motor are determined by the radial sliding bearing, and the axial position and stress of the rotor of the motor are determined by the single-row deep groove ball bearing, so that the problem of axial move
