Active Magnetic Bearing

An active magnetic bearing supports a rotor without normal running contact by regulating magnetic forces in response to measured rotor position. Electromagnetic actuators, sensors, a controller and power amplifiers form a closed control loop. The bearing provides controlled support forces; the motor or turbine supplies the rotational torque.

Active Magnetic Bearing (AMB) Turboexpander

An active magnetic bearing turboexpander is a rotating machine in which gas expands through a turbine while a feedback-controlled magnetic system supports the shaft. The turbine converts part of the gas stream's available expansion energy into shaft work. A coupled generator or compressor receives that work; the magnetic bearings control rotor position rather than create the expansion energy.
