Device enhancing steadiness of a fan between stator set and rotor thereof

Abstract

A device enhancing steadiness of a fan between stator set and rotor thereof comprises a fan stator set and a fan rotor. The hub part of the fan rotor is joined with a magnetic piece to absorb a metal element attached to the coil of the fan stator to reduce the fan rotor swaying during rotating so as to enhance steadiness of the fan and to reduce generated noise.

1 . A device enhancing steadiness of a fan between stator set and rotor thereof, comprising: 
 a frame;    a fan stator set, being provided on the frame, having a coil and a metal element on the coil; and    a fan rotor, being movably joined to the stator and having a hub part;    characterized in that the hub is joined with a magnetic piece to absorb the metal element;    whereby, steadiness of the fan during rotating can be enhanced and noise during rotating can be attenuated.    
   
   
       2 . The device enhancing steadiness of a fan between stator set and rotor thereof as defined in  claim 1 , wherein the magnetic piece is mounted at the inner bottom of the hub part on the rotor.  
   
   
       3 . The device enhancing steadiness of a fan between stator set and rotor thereof as defined in  claim 1 , wherein the hub part is provided with a fixing part at an outer circular surface and the magnetic piece is disposed in the fixing part.  
   
   
       4 . A device enhancing steadiness of a fan between stator set and rotor thereof, comprising: 
 a fan stator set, having a coil and a metal element attached to the coil; and    a fan rotor, being movably joined to the stator set;    characterized in that the hub part is made of magnetic material to be capable of absorbing the metal element;    whereby, steadiness of the fan during rotating can be enhanced and noise during rotating can be attenuated.
