PURPOSE: A BLDC(brushless DC) motor is provided to easily rotate a rotation cover by forming a protrusion on the rotation cover. CONSTITUTION: A casing is in the shape of a cylinder and has an opened one end. A stator is fixed to the inner circumferential surface of the casing.A coil is wound around the stator. A rotor with a magnet is rotationally installed in the inside of the stator. A printed circuit board has a hall sensor detecting the position of the rotor by sensing the magnetism of the magnet. A casing cover has a through hole. An annular protrusion is inserted into the through hole. A rotation cover is rotationally combined with the casing cover to close the through hole. |
