Technology and key benefits
Active magnetic bearings operate with no surface contact eliminating bearing friction and wear. Electromagnets generate forces in radial and axial directions to levitate the shaft, allowing it to rotate contact-free. A control system actively monitors and continuously adjusts the current in the electromagnets to maintain shaft position. Their extreme precision and stability makes them suitable for a much wider operating range than conventional bearings.
SKF S2M Magnetic Bearings have been making these design and performance possibilities a reality for more than two decades.
- higher reliability and energy efficiency
- virtually maintenance-free, reduced cost of operation
- oil-free and contamination-free
high damping properties, withstand high transient loads
- allow active control of the shaft unbalance
instantaneous and unlimited start/stop
- operate in vacuum and in process gas, enabling sealed machines design
built in monitoring system
Applications of the SKF magnetic bearings and high speed motors are listed in the Beyond Zero porfolio of SKF products and solutions that allow our customers to address environmental challenges, such as energy efficiency and environmental contamination.
