Tiny Cooling Fan balanced rotor axis where

Rotor imbalance will make "Tiny Cooling Fan" vibrate when the fan rotor shaft due to the physical center of mass and center of inertia of the rotor is not on the same axis, they cause the rotor imbalance. The nearest centroid of the physical distance between the rotor and the bearing is called the eccentricity of the center of inertia, when the rotor is rotated to generate a force due to the centrifugal force are formed in the shaft mount vibration, and the mechanical vibration is transmitted to each part via the base path.
   The formula for the centrifugal force: F = mr ω2 = Meω2
 Where F: centrifugal force m: mass imbalance r: unbalanced mass produced and the shaft center distance of ω: rotor speed M: total weight of the rotor e: rotor eccentricity
Vibration "Tiny Cooling Fan" on the imbalance quality should be controlled and balanced development of grade standards, not only reduces vibration "Tiny Cooling Fan" life, but will increase the fan operation noise or abnormal sound. Responsible vendors whose fan heater products in the factory are to be detected vibration, balancing machine be corrected using a microcomputer for those who exceed the balance rating.
