How do active magnetic bearings work in compressor?

Active magnetic bearings (AMBs) in compressors use electromagnetic forces to levitate and stabilize the rotor without physical contact. By continuously adjusting the magnetic field generated by electromagnets based on real-time feedback from sensors, the AMBs maintain precise rotor positioning. This technology reduces friction, wear, and energy consumption, leading to improved efficiency and reliability in compressor operation. Additionally, it allows for higher rotational speeds and reduced maintenance requirements compared to traditional mechanical bearings.
