On the theory and application of magnetic bearings
International Multi-Conference on Systems, Sygnals & Devices, 2012There is a brief introduction to some theoretical basics of magnetic bearings: losses, dynamic performance and types of magnetic bearings. Several new applications of magnetic are described: like high speed (140000 rpm) torque measuring system, ventilator test machine, cooling water pump in a power station and bearings with extreme loads in the range ...

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

Physica C: Superconductivity, 2002
Abstract Radial HTS magnetic bearings (SMB) up to 200 mm size are developed and tested in prototype fast rotating machines to demonstrate the potential to replace conventional bearings. The individual rotational bearing components HTS and PM, their physical interaction and technology is reviewed.

Journal of Magnetism and Magnetic Materials, 2004
Abstract The paper presents a special design of a passive magnetic bearing with permanent magnets on the fixed and the rotating part of the bearing. Peculiarity of the presented passive magnetic bearing is its ability to take radial and axial loads in both directions by using axially magnetized permanent magnets.

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 ...

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 ...

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 ...
