WIPO Patent Application WO/2022/121413

A1

The present application provides a power assembly and a fan. The power assembly comprises a first packaging cover, a stator assembly, a first rotor assembly, and at least two supporting components; the first packaging cover is buckled on one side of the stator assembly; a first channel is formed in the stator assembly; the first rotor assembly comprises a first rotating shaft and a first rotor; the first rotor is connected to the first rotating shaft; the first rotor can drive the first rotating shaft to rotate; the first rotor is provided at one side of the stator assembly; an axial air gap is formed between the first rotor and the stator assembly, and a second channel is formed in the first rotating shaft; first supporting components are connected to the first rotating shaft, are provided in the first channel, and are connected to the stator assembly; and second supporting components are connected to the first rotating shaft and connected to the first packaging cover. According to the power assembly provided by the present application, particularly for the power assembly needing to rotate at a high speed, at least two supporting assemblies can better share a force borne by the first rotating shaft, and thus, the axial strength of the first rotating shaft is improved.
