Abstract
The present invention discloses an outer-rotor brushless motor and a housing thereof. The housing is applicable to an outer-rotor brushless motor. The outer-rotor brushless motor includes a spindle, a stator holder mounted on a lower portion of the spindle through a bearing, and an outer rotor assembly fixedly mounted on an upper portion of the spindle. The housing comprises a cavity with a bottom being open, and covers the outer rotor assembly. At least one platform extends outwards from a bottom of a side wall of the housing, and is detachably fixed to the stator holder to form air inlet gaps. Multiple air outlet openings corresponding to the outer rotor assembly are formed in the side wall of the housing in a circumferential direction. The motor can be effectively protected and cooled.
