SKF has launched a new magnetic system which is an oil- and contact-free drive solution for centrifugal compressors in chillers. Combining a high speed permanent magnet motor and active magnetic bearings with integrated controls, the magnetic system can operate with variable speed drives to deliver energy savings of at least 10% versus conventional centrifugal compressors. In addition, the system’s vibration- and friction-free performance results in extremely low noise.
Electromagnets levitate the compressor shaft, allowing it to rotate without contact. By eliminating the mechanical contact and the losses that occur with oil-lubricated bearings, the magnetic system reduces energy use significantly. By eliminating the need for oil lubrication, the system also improves heat transfer efficiency in the evaporator and condenser.
The permanent magnet motor at the heart of this SKF solution is more energy-efficient than induction motors at full and partial loads and offers a higher power factor and lower current draw. It also operates with a smaller size variable speed drive than induction motors. The system’s active magnetic bearings are capable of speeds in excess of 40 000 rpm, and can accommodate instant and frequent startups and transient surge forces. An active control system tracks and maintains rotor position to within a micron-sized orbit up to 15 000 times per second, eliminating vibration.
High speed permanent magnetic motor solutions from SKF utilise technology pioneered by S2M, a leading producer of magnetic bearings and high speed permanent magnet motors. Acquired by SKF in 2007, S2M has been refining contact-free, levitating bearing technology for more than 30 years.
