Magnetic Bearings

Superior Performance

For more than three decades, Waukesha Magnetic Bearings has applied proven magnetic bearing technology to advance the performance of rotating equipment. We lead the industry in custom-engineered active magnetic bearing (AMB) systems for large turbomachinery and high-performing rotating equipment.

Our robust AMB systems have achieved 99.9% availability without special redundancy provisions, making them the standard for mission-critical applications. We leverage the intelligence of magnetic bearing systems and the remote connectivity capabilities of our third generation controllers to allow for machine commissioning, diagnostics and adjustment on-demand from a remote location.

Serving Demanding, Remote Locations

The high reliability and availability of Waukesha AMBs, combined with the capability for remote support, make our systems particularly suitable for remote, unmanned locations.

In addition, the elimination of the oil system inherent in the AMB design offers environmental benefits and reduces the overall footprint of equipment.

Common applications include onshore, offshore and subsea oil & gas operations; petrochemical processes; nuclear power generation; as well as renewable and developing technologies.

Lower Your Total Cost of Ownership

Advanced AMB technologies eliminate auxiliary equipment, lower energy consumption, minimize maintenance, and maximize reliability, providing cost savings throughout the life-cycle of your machinery.

Active magnetic bearing radial bearing


Magnetic bearing hardware typically includes active magnetic axial and radial bearings, auxiliary bearings, and position sensors. Depending on the corrosivity of the process fluid environment, Waukesha Magnetics Bearings can provide sealed or canned magnetic bearings.
Zephyr AMB controller


Complex control algorithms provide optimized system performance and efficiency, and remote connectivity capabilities integrated into our advanced digital controllers allow for remote commissioning, monitoring, diagnostics and adjustment.
Automated commissioning for active magnetic bearing systems


Our unique system support reduces operating expenses and logistical headaches. While the conventional approach to commissioning and maintenance requires onsite support, Waukesha facilitates these remotely and trains customers to perform many routine functions.

How Magnetic Bearings Work

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.
