Document Type and Number:
WIPO Patent Application WO/2024/021501
Kind Code:
A1
Abstract:
The present invention relates to a motor, comprising a rotating shaft extending in the axial direction, an inner rotor fixed to the rotating shaft, an outer stator sleeved on the outer periphery of the inner rotor, a fan fixed to the rotating shaft, and an air guide cover located between the outer stator and the fan. The air guide cover comprises a first air guide ring located at the rear end in the axial direction and a second air guide ring located at the front end in the axial direction; the fan is located in the second air guide ring; the first air guide ring is arranged adjacent to the outer stator, and the first air guide ring has an inner diameter of d3; the outer stator has a first inner diameter of d1, wherein the inner diameter d3 of the first air guide ring is larger than or equal to the first inner diameter d1 of the outer stator. The heat dissipation effect is significantly improved.
