Micro Cooling Fan blade balance

"Micro Cooling Fan" leaves the balance between the performance of the entire DC fan, DC fan blade balance than being commonly used dynamic balance, it is the principle of adjustable vanes for DC fans and single-stage rotor blade adjustable DC fans, Because only one level of the impeller, mass imbalance so because "Micro Cooling Fan" caused by wear on the impeller are concentrated in its balancing process is a single plane balancing process, namely static equilibrium process. If it is determined the vibration caused by mass imbalance, so long as the measurement point of the horizontal or vertical direction in the vicinity of the bearing housing shell vibration, use of influence coefficient method, increase in the impeller, you will be able to reduce the "Micro Cooling Fan" Fan Vibration to within the desired range.
