  • Patent number: 8497610
    Abstract: A ceiling fan motor has a stator with several coil arms disposed at intervals for the winding of magnetizing coils. Between two adjacent coil arms are formed with a magnetic pole spacer. A supporting base is provided in a predetermined magnetic pole spacer for the disposition of a sensor to detect the position of the rotor.

  • Publication number: 20110280734
    Abstract: A combining structure for the decorating shell of a ceiling fan includes an outer shell and a decorating cover. The bottom of the outer shell has a connecting hole. The rim of the connecting hole is formed upward with at least two opposite notches. Each of the notches is bent downward with a blocking rim that gradually converges. The decorating cover has an annular shape, and is mounted on the bottom of the outer shell. The inner rim of the decorating cover is protruded upward with an inner rim wall that goes through the connecting hole of the outer shell. The outer surface of the inner rim wall is protruded outward with a protruding part for each of the notches on the outer shell. The protruding parts go through the notches and urge and position on the blocking rim at the bottom of the outer shell.

  • Publication number: 20110280733
    Abstract: A structure of the decorating shell for a ceiling fan includes an outer shell and a decorating cover. The bottom of the outer shell has a connecting hole. The surrounding surface at the bottom of the outer shell has at least two opposite grooves. The decorating cover has an annular shape and is correspondingly disposed at the bottom of the outer shell. The outer rim of the decorating cover is protruded upward with hook parts to engage with the grooves. At least one elastic body is interposed between the inner rim and the outer rim of the decorating cover. When the decorating cover is mounted onto the bottom of the outer shell, the elastic body is squeezed by the outer shell and the decorating cover to urge against the surrounding surface at the bottom of the outer shell.

  • Publication number: 20110249456
    Abstract: One end of a lamp support is defined as a mounting end, and the other end is defined as a connecting end. The mounting end connects to a lamp box, and the connecting end connects to a lamp base. The mounting end of the lamp support has a through hole. The tip of the mounting end is bent to form a hook section. The lamp box has a mounting hole and a groove in a shape corresponding to the hook section. An inserting element is inserted into the through hole of the mounting end and the mounting hole of the lamp box, thereby mounting the lamp support onto the lamp box. The hook section of the mounting end correspondingly catches the groove of the lamp box, fixing the lamp support.

  • Publication number: 20100124504
    Abstract: A structure of blade and blade frame for a ceiling fan is disclosed. The inserting parts of a blade frame go through the through holes on a blade. Each inserting part has a stopping part exposed from the blade. An elastic positioning element connects several limiting parts using linear linking parts. The limiting parts urge against the stopping parts in opposite directions, providing constraints between the stopping parts and the blade and, thereby, combining the blade and the blade frame.
