Light cover assembling structure of a ceiling fan

A light cover assembling structure has a light housing, a mounting sleeve, a light-emitting element, a transparent light cover, and a supporting cover. The mounting sleeve has an inner end mounted in the light housing and an outer end extending out of the light housing. An inner surface of the light housing and an outer surface of the mounting sleeve form an assembling space. The transparent light cover is mounted on the outer end of the mounting sleeve. The supporting cover is mounted on the outer end of the mounting sleeve, and has a first supporting side wall formed circumferentially and abutting the transparent light cover. The first supporting side wall of the supporting cover supports the transparent light cover such that the transparent light cover is firmly mounted on the mounting sleeve.

Fan, permanent magnet synchronous motor and stator structure

The utility model relates to a fan, a permanent magnet synchronous motor and a stator structure. The stator structure comprises a body and at least two convex teeth which surround the outer wall of the body and are arranged at intervals, an auxiliary groove which is formed in the axial direction of the body is formed in the tooth top face of each convex tooth, and each auxiliary groove is provided with a first side wall and a second side wall which are oppositely arranged; the distance between the first side wall and the second side wall is gradually reduced in the direction close to the body. The auxiliary grooves are formed in the tooth top faces of the convex teeth arranged around the body in the circumferential direction; moreover, the distance between the opposite first side wall and second side wall of the auxiliary groove is gradually reduced along the direction close to the body, so that the path of a magnetic line of force can be changed, tooth harmonics among different convex ...

Ceiling fan light kit

Ceiling fan

A ceiling fan, including: a rotary shaft, a stator, and a rotor. The rotor includes an inner annular chamber, a magnetic-shoe fixation portion, a connection portion, and a bearing installation portion. The stator is housed in the inner annular chamber of the rotor. The bearing installation portion is disposed at one side of the magnetic-shoe fixation portion. One end of the connection portion is fixed on the magnetic-shoe fixation portion, and the other end of connection portion is fixed on the bearing installation portion. The magnetic-shoe fixation portion, the bearing installation portion are integrated with the connection portion. The geometric centers of the rotary shaft, the stator, the magnetic-shoe fixation portion, and the bearing installation portion are located in a straight line.
