Title:
WHEEL MOTOR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/210990
Kind Code:
A1
Abstract:
The present invention relates to a wheel motor structure which has enhanced dustproof and waterproof effects and, simultaneously, can have increased heat radiation efficiency. Disclosed is the wheel motor structure comprising: a stator; a rotor; a cover coupled to one side of the rotor such that one side of the stator is covered; a coupling shaft penetrating each of the stator and the cover; and an oil seal disposed in the space between the cover and the coupling shaft so as to seal the space, wherein the cover has heat-radiating fins extending in the radial direction and protruding from both surfaces thereof. Therefore, the wheel motor structure has enhanced dustproof and waterproof effects and, simultaneously, can have increased heat radiation efficiency.
