Abstract
A waterproof and dustproof fan motor structure includes a base, an annular enclosure, and a stator assembly. The base has a vertically forward extended bearing cup; the annular enclosure internally defines a closed annular space and is externally fitted around the bearing cup; and the stator assembly is disposed in the closed annular space of the enclosure. The waterproof and dustproof fan motor structure can be assembled to a frame and a rotor assembly to complete a fan. With the stator assembly disposed in the closed annular space of the enclosure, the fan motor is protected against damage caused by moisture and dust, and the stator assembly can be easily removed from the closed annular space for necessary maintenance and repair to thereby reduce the bad yield and the manufacturing cost of fan and fan motor.
