ABSTRACT:
A motor includes a first housing, a second housing, a rotor and a stator. The second housing is assembled with the first housing to form an accommodating space. The second housing has a flange adjacent to the connection between the first and second housings. The rotor has a shaft extended outwardly from the second housing and disposed in the accommodating space. The stator is disposed corresponding to the rotor and in the accommodating space. The flange has at least one protruding portion. When the second housing is assembled with the first housing, the protruding portion presses against the stator and is deformed so that the first and second housings are sealed.
