In this embodiment, the motor 100 further includes a rotor 160, the rotor 160 is located on the peripheral side of the stator 110, and the rotor 160 and the stator 110 are connected and relatively rotated by a first bearing 170 and a second bearing 180.

Further, along the axial direction of the stator 110, the first bearing 170 and the second bearing 180 are arranged at intervals, so that the connection points between the stator 110 and the rotor 160 are uniformly distributed, the stator 110 and the rotor 160 are more stable in relative rotation, and the operation of the motor 100 is prevented from being failed. Meanwhile, the arrangement increases the contact area and the contact angle between the rotor 160 and the stator 110, which is beneficial to ensuring the stability and reliability of the rotor 160 driven by the stator 110.

Further, the first bearing 170 may be located between the wire clamp 130 and the rotor 160, and by disposing the first bearing 170 between the wire clamp 130 and the rotor 160, the first bearing 170 may be pressed in the axial direction of the stator 110 while the connection between the rotor 160 and the stator 110 is achieved, and the first bearing 170 further fixes the wire clamp 130 to the stator 110, thereby further improving the stability of the connection between the wire clamp 130 and the stator 110, preventing the wires 120 from scattering outside the stator 110, and further improving the stability of the motor 100.

Meanwhile, the device has the function of collecting flow, reduces the frequency of phenomena of airflow flow separation, vortex and the like, is beneficial to reducing the operation noise of the air supply device, and can improve the service performance of products.

In other embodiments, the structure of the channel may be reasonably arranged according to the layout of the internal components of the air supply device, for example, the channel is arranged in a bent manner, or the channel includes a plurality of connected bent tube bodies. The stator comprises a first end face and a second end face which are oppositely arranged along the axial direction of the stator, the first end of the channel is arranged on the first end face, and the second end of the channel is arranged on the second end face.

That is, the structure of the channel can be set according to actual needs to meet diversified use requirements.
