A magnetic bearing. A magnetic bearing is a type of bearing that supports a load using magnetic levitation. Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear. Magnetic bearings support the highest ...
Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
An active magnetic bearing (AMB) works on the principle of electromagnetic suspension and consists of an electromagnet assembly, a set of power amplifiers which supply current to the electromagnets, a controller, and gap sensors with associated electronics to provide the feedback required to control the position of the rotor within the gap ...
Electrodynamic bearings (EDB) are a novel type of bearing that is a passive magnetic technology. EDBs do not require any control electronics to operate. They work by the electrical currents generated by motion causing a restoring force.
The North American Maglev Transport Institute (NAMTI) is a non-profit organization based in Washington, DC, USA, and established to educate the public about the advantages of magnetic levitation (maglev) transport. [1]
American Maglev Technology (AMT), sometimes referred to as just American Maglev, is an American company founded in 1994 [1] focused on creating maglev systems for public transit based in Amelia Island, Florida [2] [3] with former locations in Mariette, Georgia, [4] [5] and in Volusia County, Florida.

The National Maglev Initiative (NMI) was a research program undertaken in the early 1990s by the United States Department of Transportation, U.S. Army Corps of Engineers, Department of Energy, and other agencies which studied magnetically levitated, or "maglev", train technology, operating at speeds around 300 miles per hour (480 km/h).
