Chinook Controller
High-Power Digital Controller
Available as a single- or dual-bay cabinet, the Chinook® controller is a high-power digital magnetic bearing control system recommended for rotating machinery in the power range 10 MW to 25 MW.
The controller provides simple and fail-safe integration of the control cabinet with the machine station via digital output/input, and its high processing performance allows for complex algorithms that provide high dynamic efficiency and noise immunity.
The controller also offers an automated commissioning and tuning process, built-in condition monitoring and remote adjustment capabilities.

Magnetic Bearings Exceed 95% Availability in Pipeline
After bitter experience with other compressor stations in frigid locations, Gazprom sought ways to improve compressor operations. Our robust AMB systems, utilizing a dual-bay Chinook controller, were able to increase reliability and availability, as well as improve integration with the compressor station.
Typical Applications
- High-temperature gas-cooled reactor (helium use)
- Natural gas pipeline compressors
- Energy recovery flywheel
- Loop layer machine
- Sour gas with canned or sealed bearings
