Active balancing

Ring Balancer AB 9000

AB 9000 is the innovative active balancing system for the automatic balancing of all types of rotors.

Ring Balancer AB 9000
  • Features
    • Automatic (active) balancing of rotors (e.g. grinding wheels, grinding spindles, turning chucks, fans) in one or two planes with unbalance monitoring.
    • Active balancing during operation without having to stop the machine.
    • Ring shaped balancing unit for efficient, space-saving integration into the rotor.
    • Balancing to very high rotational speeds in very short time by fast electro-magnetic actuator and adaptive balancing process.
    • Non-contact, wear-free transmission of energy for the actuator positioning the balancing weights.
    • Pre-balancing software for manual correction of basic unbalance; AB 9000 then only balances the new operational unbalances.
    • Neutralising of balancing unit possible, e.g. for pre-balancing.
    • Indication of remaining balancing capacity.
    • PC operation software
  • Applications
    • Automatic (active) balancing of all types of rotors.
    • Balancing during operation without having to stop the machine.
    • Inducing test unbalances for system identification
    • Generating unbalances during acceptance test.
