External rotor motor

Disclosed in the utility model is an external rotor motor comprising a rotor, a stator, and a rotating shaft. The rotating shaft is installed at the center of the rotor and cooperates with the stator by two bearings installed at the stator center hole. The rotating shaft and the rotor are connected by a shaft sleeve fixed at the rotor; and the two bearings are single-row tapered roller bearings. According to the scheme, a casing tube fixed at the center of the stator is used for installing the bearings, so that the concentricity of the two bearings is ensured, the bearing is not easy to vibrate, and the vibration and noises of the external rotor are reduced. The bearings use the tapered roller bearings, thereby improving the bearing service life and lowering the maintenance cost.
