Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the dc brushless magnetic rotor stabilizing device for a ceiling fan motor shown in the drawings comprises a brushless magnetic rotor body 1, a housing 3 and a stabilizing mechanism 4, wherein a rotating shaft 2 is fixed in the brushless magnetic rotor body 1, the housing 3 is sleeved outside the brushless magnetic rotor body 1, the top end and the bottom end of the housing 3 are rotatably connected with the rotating shaft 2 through bearings, and the stabilizing mechanism 4 for improving the stability of the rotating shaft 2 in the brushless magnetic rotor body 1 is installed outside the bottom end of the rotating shaft 2 and is located at the bottom of the housing 3.

The stabilizing mechanism 4 comprises a connecting sleeve 5 and a conical sleeve 6, the connecting sleeve 5 is fixed on the outer side of the bottom end of the rotating shaft 2, a plurality of mounting grooves 7 are formed in the outer side of the connecting sleeve 5, adjusting pieces 8 are mounted in the mounting grooves 7, the conical sleeve 6 is sleeved on the outer side of the rotating shaft 2 and fixed with the bottom of the shell 3, and the conical sleeve 6 is reversely buckled at the bottom of the shell 3;
