The active magnetic bearing (AMB) is an integral part of the industrial rotational machine. The paper deals with simulation study of three and four coil AMB utilizing Finite Element Method (FEM). This paper also presents how ANSYS software (Ver. 12.1) can be used to perform the magnetic field analysis in the AMB. This work reports ANSYS simulation for two different structure of AMB that uses th...

The magnetic-liquid double suspension bearing (MLDSB) is a new type of bearing, with electromagnetic as the main part and hydrostatic supports auxiliary part. It can greatly improve capacity stiffness rotor-bearing systems suitable for medium speed, heavy load, frequent starting occasions. Compared active system, traditional protective device replaced by system in MLDSB, impact-rubbing phenomen...

Active magnetic bearing (AMB) system has been recently employed widely as an ideal equipment for high-speed rotating machines. The inherent challenges to control the include instability, nonlinearity and constricted range of operation. Therefore, advanced technology is essential optimize AMB performance. This paper presents application model predictive (MPC) based on linear parameter-varying (L...
