Three different technical solutions delivered the following large energy savings in industrial compressors; Savings of 700,000 kWh peryear were made when SKF magnetic bearings replaced hydrodynamic bearings in a 12MW natural gas pipeline compressor. That is the equivalent of the total energy consumption of 900 Swedish homes for one month. In addition there are cost and environmental benefits gained by eliminated oil related systems; pumps, coolers, filters and the need to dispose of used oil. Magnetic bearings deliver torque by a shaft suspended in a magnetic field that can be controlled to vary the speed of rotation. The shaft has no contact with any other machine parts making the system almost friction-free.
