1. A fan comprising:
a motor comprising:
at least one stator assembly comprising a stator yoke portion and at least one stator tooth,
wherein the stator yoke portion and the at least one stator tooth are detachably connected to each other,
wherein the stator yoke portion is provided with a stator yoke slot adapted to a shape of the at least one stator tooth,
wherein the at least one stator tooth comprises a stator tooth body that is inserted into the stator yoke slot to form a stator core, and
wherein the stator tooth body extends from the stator yoke portion in an axial direction of the stator core;
at least one rotor arranged correspondingly to the at least one stator assembly; and
at least one winding wound on the stator tooth body of the at least one stator tooth;
a first fan blade;
a first rotating shaft connected to one of the at least one rotor to extend in the axial direction of the stator core,
wherein the first fan blade is arranged at one end of the first rotating shaft and is rotated by rotation of the first rotating shaft; and
a positioning groove and a positioning rib adapted to each other in the shape of the at least one stator tooth,
wherein:
one of the positioning groove and the positioning rib is arranged on the at least one stator tooth, and the other of the positioning groove and the positioning rib is arranged on the stator yoke slot so as to limit a position of the at least one stator tooth at the stator yoke portion; and
the positioning rib protrudes along a radial direction of the stator core.
