Higher voltage gives increased performance

FAG Active Magnetic Bearings are monitored by intelligent assessment systems from Schaeffler.


FAG's Bearings are available with 14 A to 150 A inverters with an intermediate circuit voltage of 540 VDC. This allows larger air gaps in the magnetic bearing and electronics to be adapted according to customer's specific requirements. The dynamic load carrying capacity of the magnetic bearing can be increased by using higher currents for a constant voltage.

Schaeffler's electronics fulfil the drive technology industry standard and are compatible with all the current bus systems and interfaces. The adaptability of the electronics in the FAG Active Magnetic Bearing means customers can control the magnetic bearing's operation themselves instead of having separate power electronics for each process.

Rolling bearings are fitted as back-up bearings. If a 'touchdown' or shaft drop occurs, the bearing's status can be quickly checked using the FAG ProCheck condition monitoring system. This reduces machine downtime.

Schaeffler's remote monitoring allows defects and damage in machines to be recognised at an early stage so that the relevant countermeasures can be put in place in time without a machine operative having to be on hand. This impacts both Overall Equipment Effectiveness (OEE) as well as Total Cost of Ownership.
