Abstract
The utility model discloses a direct-current motor used for a decorative ceiling fan. The direct-current motor comprises a shell and an upper cover fixedly fitted and connected with the shell. The shell and the upper cover are both provided with bearing installation holes, and bearings are fitted in the bearing installation holes. The shell is internally provided with a stator which can rotate relative to the shell. The stator is uniformly provided with multiple groups of magnet exciting coils in the peripheral direction. The stator is fixedly connected with a rotating shaft matched with the bearings. An integrally-formed circular ring-shaped magnet is arranged between the shell and the stator. The circular ring-shaped magnet is fixedly connected with the shell. The integrally-formed circular ring-shaped magnet is adopted and the circular ring-shaped magnet is fixedly connected with the shell and the upper cover to form a rotor. During the work, the circular ring-shaped magnet, the shell, and the upper cover rotate with respect to the stator. The direct-current motor is characterized by being convenient in assembling and being cost-saving; and simultaneously, the direct-current motor is capable of preventing the generation of resonance vibration and reducing noise.
