SKF Magnetic System

Energy-efficient solution for centrifugal air conditioning compressors

Building on the performance advantages of magnetic bearings, the SKF Magnetic System provides a cost and energy-efficient solution for centrifugal air conditioning compressors. The solution combines magnetic bearings with a permanent magnetic motor, plus an integrated control system and a variable speed drive.

Higher reliability with SKF magnetic bearings

Electromagnets hold the shaft in a levitated position so the shaft rotates without contact. A control system monitors shaft position and adjusts the current in the bearing coils to maintain stable control of the shaft. Oil, lubrication and contaminant-free, SKF magnetic bearings are very well suited for use in refrigeration compressors. As part of the SKF Magnetic System, SKF magnetic bearings help enable:
  • A 10%+ increase in energy efficiency vs. conventional bearings
  • Reduced maintenance demands and costs
  • No oil residue – zero contamination
  • Significant noise reduction
