Active magnetic bearings
Position feedback and electromagnetic force maintain controlled rotor levitation during operation.
Technology architecture
Oil-free rotation, actively controlled.
Active magnetic bearings support the rotor without an oil-lubricated bearing system, while the compressor, drive and bearing controls operate as one engineered platform.

- Magnetic bearings
- Variable-frequency drive
- Centrifugal compressor
- Thermal management
Four linked layers
A compressor platform, not an isolated rotor.
Each layer must be considered together during OEM selection, system controls design and validation.
Two-stage gas path
Catalog-described two-stage architectures support the published S, T and H product families.
Integrated BMCC
The catalog presents the drive, compressor and bearing controls as an integrated control architecture.
Power-loss response
A self-generation approach is described for controlled deceleration and zero-speed landing after power loss.
Control sequence
Sense, calculate, actuate.
This simplified loop explains the role of an active magnetic-bearing controller. Project documentation defines the actual control and protection implementation.
- 01
Measure position
Sensors monitor rotor displacement relative to the commanded position.
- 02
Calculate correction
The bearing controller evaluates the feedback signal and operating state.
- 03
Adjust magnetic force
Electromagnet current is modulated to maintain controlled levitation.
Evidence boundary
Published figures require model and test context.
The current product catalog includes component-level values for bearing loads, motor speed, sensor response and levitation precision. These are supplier-published values until paired with a model, test condition, method and report.
