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.
