Passive magnetic bearings with permanent magnets
IEEE Transactions on Magnetics, 1978The various geometrical dispositions which allow to realize passive magnetic bearings with permanent magnets, have been Known for several decades. Devices running by attraction were the first to be built. When new magnets, which can be used in repulsion appeared on the market (SmCo 5 ), new types of passive magnetic bearings, running by repulsion ...

The analysis of the behaviour of Passive Magnetic Bearing in order to achieve an acceptable magnetic force and stiffness is an interesting topic for rotating systems. Numerical analysis, which is an effective method to investigate the structural parameters of PMB, is applied using Finite Element Method to the two-dimensional model of Passive Magnetic ...

Rotor Bearing System Design on Magnetic Bearings
Volume 3B: 15th Biennial Conference on Mechanical Vibration and Noise — Acoustics, Vibrations, and Rotating Machines, 1995Abstract The rotordynamic analysis of a high speed multistage centrifugal compressor supported on radial magnetic bearings, which has been running successfully in the field for 9000 hours to date, is presented. Iterations required to achieve an acceptable rotor configuration using magnetic bearings are discussed. The results of the rotor-

Fundamentals of Magnetic Bearings
2013Active magnetic bearings (AMBs) are non-contact bearings for rotating machines. A pair of electromagnets acting at opposite sides of the rotor balance the attractive magnetic forces in order to center the rotor in the control axis. Some fundamental concepts and terminologies that are needed for describing the operation and modeling of active magnetic ...

In this paper a Permanent Magnets (PMs) magnetic bearing capable to rotate at a short distance from a dedicated stator is presented. The magnetic suspension is assured by the repulsion of properly shaped PMs on both the stator and the rotor. The presence of eddy currents on a conducting sheet surrounding the stator magnets helps in overcoming the ...
