If it is determined "220V Cooling Fan" vibration is caused by a 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, will be able to reduce fan vibration within the ideal range. "220V Cooling Fan" blade balance between the performance of the entire DC fan, DC fan blade balance than being commonly used dynamic balance, it is the principle of the stationary blade adjustable "220V Cooling Fan" and single-stage rotor blade adjustable DC fans, because only one level of the impeller, mass imbalance caused due to wear it all focused on the impeller, the balancing process is a single plane balancing process, namely static equilibrium process.
