The dynamic balancing machine is used to measure the size and position of the unbalance of the rotating object (rotor).  The main performance of the dynamic balancing machine is to use two comprehensive indicators: the minimum achievable residual unbalance and the reduction rate of the dynamic balancing machine. The former is the minimum residual unbalance that the balancing machine can make the rotor reach. It is a measure of the highest balance of the balancing machine. An indicator of capability; the latter is the ratio of the amount of imbalance that is reduced after one correction to the amount of initial imbalance.
An unbalanced rotor produces a stress on its support structure and the rotor itself during its rotation, and causes vibration. Therefore, the dynamic balance of the rotor is very necessary, and the balancing machine is the dynamic balance test of the rotor in the rotating state.
The role of dynamic balance is to:
1. Improve the quality of the rotor and its components; reduce noise;
2. Reduce vibration;
3. Improve the service life of supporting components (bearings);
4. Reduce the discomfort of users;
5. Reduce the power consumption of the product.
