Transient response technique applied to active magnetic bearing machinery during rotor drop
The active magnetic bearing (AMB) is a relatively new technology which has many advantages compared with conventional bearing design. In an AMB system, the rolling-element back-up bearings are indispensable to protect the magnetic bearing rotor and stator, and other stationary seals along the rotor …

Finite element based non-linear transient analysis of active magnetic bearing turbomachinery
The active magnetic bearing (AMB) is a relatively new technology in which the suspension forces are generated magnetically without any contact. Although there are many advantages of AMB technology over conventional bearing design, its major selling point is the claim of reduced maintenance and …

The Experimental Testing of an Active Magnetic Bearing/Rotor System Undergoing Base Excitation
Active Magnetic Bearings (AMB) are a relatively recent innovation in bearing technology. Unlike conventional bearings, which rely on mechanical forces originating from fluid films or physical contact to support bearing loads, AMB systems utilize magnetic fields to levitate and support a shaft in an …

Internal Torques and Forces in Gyrostats with Magnetically Suspended Rotors
Active magnetic bearings have several potential applications in spacecraft design. Based on the gyrostat model, we develop equations that describe the internal torques and forces that occur between the body and one of the attached wheels. We evaluate the transverse torques for the torque--free …
