Waterproof motor stator structure

A waterproof motor stator structure, comprising:

• a circuit board;
• a stator being mounted on one face of the circuit board and electrically connected to the circuit board;
• a lower shell having an open-topped annular recess formed on one side thereof for receiving the circuit board therein, and an opening located at a center of the lower shell and communicable with the annular recess;
• an upper shell being located on the face of the circuit board having the stator mounted thereon and fitted around an outer side of the stator;
• the upper shell having an open lower end defining a first opening and a partially open upper end providing a second opening;
• and the first opening being communicable with the second opening of the second shell and the central opening on the lower shell;
• and
• a protective layer being formed in the annular recess to encapsulate the circuit board and the open lower end of the upper shell, and accordingly joining the lower shell and the upper shell into an integral unit.
