Waterproof motor stator structure
A waterproof motor stator structure includes a circuit board; a stator mounted on one face of the circuit board; a lower shell forming an open-topped annular recess for receiving the circuit board therein and having an central opening communicable with the annular recess; an upper shell fitted around an outer side of the stator; and a protective layer formed in the annular recess of the lower shell to encapsulate the circuit board and an open lower end of the upper shell, so that the lower shell and the upper shell are joined into an integral unit. With these arrangements, the stator located in between the lower and upper shells can be effectively protected against external moisture and salt spray with reduced time, labor and material costs while enabling extended service life a fan using same.
