Electromagnetic Balancing System EMB 7000
EMB 7000 is the innovative active balancing system for the automatic balancing of all types of rotors.
- Features
- Automatic (active) balancing of rotors (e.g. grinding wheels, grinding spindles, fans, turning chucks, rollers, turbo-machinery) 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; EMB 7000 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.
