Title:
POWER ASSEMBLY AND FAN
Document Type and Number:
WIPO Patent Application WO/2022/116239
Kind Code:
A1
Abstract:
A power assembly (910) and a fan. The power assembly (910) comprises a housing (100), a stator assembly (200), a rotor assembly (300), and a rotating shaft (400); the stator assembly (200) is disposed in the housing (100); the rotor assembly (300) is located on one side of the stator assembly (200) in an axial direction to form an axial air gap between the rotor assembly (300) and the stator assembly (200); the rotating shaft (400) has a first end connected to the rotor assembly (300), and a second end passing through the stator assembly (200) and extending to the outside of the housing (100). The rotor assembly (300) is disposed on one side of the stator assembly (200) in the axial direction of the rotating shaft (400), so that the magnetic flux direction of the power assembly (910) is the axial direction, and thus, in the case of identical output power and identical efficiency, the axial length is smaller.
