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.

Abstract: A brushless motor includes a stator assembly and a rotor assembly one coaxially disposed around the other. The rotor assembly includes a spindle and a rotor yoke coaxially disposed around the spindle. At least two magnet receiving grooves for receiving magnets are formed in an inner wall of the rotor yoke in a circumferential direction, the magnets are inserted into the magnet receiving grooves, and a magnetism isolating gap is formed between the at least two magnet receiving grooves. Through the external-rotor design, the size and weight of the motor are effectively reduced, the working efficiency of the motor is effectively improved under the same power, the life of a lithium battery is further prolonged, the energy conversion requirement is met, and user experience is improved.
