Active Balancing Intelligent Balancing Solutions Electromagnetic Ring Balancer AB 9000 • Balancing during machine • Achieving perfect running • Monitoring unbalance vibrations • Generating unbalance for system identification or acceptance tests • Ring design for universal • Time savings through fast adaptive balancing methods • Increased product quality and machine availability • Suitable for very high speeds • Permanent vibration • Neutral position for manual pre- visualisation software • Field balancing software HSC spindle with AB 9000 balancing unit The active balancing system unbalance during the operation of a machine. Therefore two balancing rotors are built into the rotating part of the balancing unit. These rotors rotate freely on the rotational axis. If the rotors' balancing weights are positioned directly opposing each other, their effect is neutralised. The full balancing capacity is obtained by placing the weights at the same angular position. By moving the weights to a specific angle, any unbalance correction with respect to obtained within the mentioned limits.

Intelligent Balancing Solutions The measured information - rotor speed, angular position of balancing rotors and vibrations - are captured by a fast controller unit using adapti- exceeds preset limits, an automatic balancing run is started. The balan- cing rotors are moved by activation System characteristics AB 9000 balances using a direct adaptive procedure. The positions of the balancing rotors required to com- calculated based on the actual mea- suring data. Thus, only a minimum number of balancing steps are requi- red not only for one plane balancing but especially if two planes need to...
