Novel magnetic spring and magnetic bearing
IEEE Transactions on Magnetics, 2003We describe a magnetic spring consisting of two magnetic rings with different dimensions, located concentrically in the same direction of magnetization. One of the two magnetic rings is fixed and the other can move axially. Because of the magnetic field, the two magnetic rings tend to keep away from each other at a fixed axial distance. If the relative

Over the past several years magnetic suspension has been emerging from the laboratory and a number of successful engineering prototypes have been constructed both here and abroad. Advances in magnetic materials, primarily Samarium Cobalt, and in electronics across the board for sensing and control, have contributed to the realization of completely non ...

Improvements of the Integration of Active Magnetic Bearings
IFAC Proceedings Volumes, 2000Abstract Functional and structural integration are tools to improve mechatronic systems that include active magnetic bearing systems. In this paper two aspects of the integration of electromagnetic bearings are presented: 1. The non-linearity of the magnetic force is compensated by software integrated in the digital controller. 2.

The application of HTSC bulk materials in magnetic bearings requires an understanding and minimization of the friction in such systems. Since the rotors in these bearings are not completely axially symmetric, their rotation generates an ac magnetic field acting on the superconductors and the metallic components of the arrangement.

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 ...

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 ...

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 ...
