Advancing the Possibilities of Magnetic Bearings
Waukesha Magnetic Bearings is proud to be partnering with L.A. Turbine (LAT) to bring the benefits of active magnetic bearings to turboexpander operators. As part of the LAT ARES AMB turboexpander-compressor, we have introduced the industry’s first skid-mounted AMB control system.
Gas processors benefit from lower CapEx, faster commissioning, decreased maintenance, a smaller footprint, improved site layout, temperature and performance flexibility, and a more environmentally friendly machine.
Hazardous Area Installation
In a conventional hazardous area installation, the AMB controller is installed in a control building in a safe area away from the machine skid, connected by expensive cabling. Costs are incurred for the cables, their design and installation. In addition, OEM testing is typically not performed with the job cables, requiring recommissioning of the AMB system at the end user site.
The Waukesha Magnetic Bearings skid-mounted AMB controller, certified for Class 1/Div 2 hazardous area installation, eliminates the costly AMB cables and simplifies plant design. Moreover, the turboexpander is ready for operation upon delivery to the site.
Built-in Condition Monitoring
Operators also benefit from the ability to perform remote commissioning, monitoring and tuning of machine performance due to the high-tech digital signal processors and control algorithms of the Waukesha Magnetic Bearings Zephyr® 5-Axis Controller.

Flexure Pivot® Journal Bearings
For high-load, high-speed, small-diameter shafts, our Flexure Pivot tilt pad design achieves low cross-coupling and high stability, while eliminating the pivot wear that can cause degradation in performance over time.
Leading Vibration Solutions
With our in-depth understanding of system rotordynamics, Waukesha Bearings offers proven solutions to improve stability and control vibrations. Chief among those solutions, our integral squeeze film damper (ISFD® technology) provides highly engineered damping and stiffness to maximize energy dissipation at the bearing locations.
Waukesha Bearings brush seals can minimize leakage gaps and increase operational efficiencies. The compliancy of a brush seal allows sealing clearances to be significantly reduced, while its low profile allows simple integration with labyrinth seals.
