Abstract
A magnetic bearing has electromagnets which are actively controlled to maintain a rotor at a prescribed position relative to a stator. Radial and axial bearings are disclosed. In each, conductive loops travel relatively through field zones which are associated with the electromagnets. Sensors provide signals indicative of deviations of the loops from their prescribed circular path, and these signals control the electromagnets selectively to change the magnetic field strengths. A loop current will be induced by the movement of a loop through a magnetic field. This current, in the presence of the magnetic field or fields will exert Lorentz forces on the loop in a radial and/or axial direction. These forces return the rotor to its prescribed position.
