The utility model discloses a brushless motor of outer rotors. This brushless motor of outer rotors includes: the apparatus further comprises a rotating shaft. With pivot fixed connection's rotor, andwith the stator of connecting is rotated in the pivot, the stator includes the base be equipped with first through -hole on the base, the pivot through two bearings install in in the first through -hole, two the bearing is located respectively the both ends position of first through -hole axial fixity has two at least stop parts in the pivot, the stop part close -fitting in the bearing so that pivot axial fixity in in the first through -hole. The utility model provides a technical problem who solves is in the present brushless motor of outer rotors rotor, thereby the rotor produces serious friction with the stator contact, can lead to the fact motor noise and vibration.
