Waukesha Magnetic Bearings designs the most robust magnetic bearings available in the industry. These systems have achieved 99.9% availability without special redundancy provisions, making them the standard for mission-critical applications.
A magnetic bearing uses electromagnetic forces to maintain relative position of a rotating assembly (rotor) to a stationary component (stator). An advanced electronic control system adjusts these electromagnetic forces in response to forces generated from machine operation.
Waukesha Magnetic Bearings leverages the intelligence of magnetic bearing systems and remote connectivity capabilities inherent to our third generation controllers to allow for machine commissioning, diagnostics and adjustment on-demand from a remote location (without the need for on-site support).
For the hardware, Waukesha Magnetic Bearings engineers sealed magnetic bearings, which can be immersed in mildly corrosive process fluid environments, as well as canned magnetic bearing systems, which are designed for immersion in the most extreme corrosive and abrasive environments.
Waukesha’s active magnetic bearing systems components include:
Waukesha Magnetic Bearings offers sealed magnetic bearings or canned magnetic bearings – each engineered to meet our customers’ unique needs.
Sealed Magnetic Bearings
Sealed bearings are designed to be immersed in a process fluid environment and are ideal for mildly corrosive environments and applications requiring high reliability and availability.
Rotor and stator laminations are made of corrosion resistant alloys or more conventional alloys protected with specialized coatings.
The sealed magnetic bearing stators and sensors have all windings, conductors and connections encapsulated for protection against liquid content. Liquid-resistant auxiliary bearings are available with these systems.
Canned Magnetic Bearings
Waukesha canned magnetic bearings are designed to be immersed in the process fluid with the most extreme corrosive and abrasive environments.
This solution is the only choice for compressor applications where the gas is contaminated with H2S, chlorides, sand, condensate and other liquids.
Canned bearing technology is also applied to pumps, steam turbines and other applications where the bearings are continuously or intermittently immersed in high-pressure, corrosive liquid environments.
The canned magnetic bearing system includes canned stators and sensors, and corrosion-resistant rotor laminations, thrust collars and auxiliary bearings. Canned stators are integrated into completely seal-welded housings without the need for elastomeric elements. Auxiliary bearings for canned magnetic bearing applications are constructed of corrosion-resistant alloys and materials to complete the entire bearing system – ready for service in the most extreme corrosive environments.
