摘要： A superconducting bearing device comprises a permanent magnet portion fixedly mounted on a rotary body concentrically therewith, and a superconductor opposed to the magnet portion and spaced apart therefrom radially of the rotary body, the magnet portion being so disposed that the rotation of the rotary body does not alter the magnetic flux distribution around the axis of rotation of the rotary body, the superconductor being disposed at a position which is spaced apart from the magnet portion by a distance permitting a predetermined quantity of magnetic flux thereof to penetrate into the superconductor and which does not permit the rotation of the rotary body to alter the penetrating magnetic flux distribution. The magnet portion comprises a plurality of annular permanent magnets arranged at a spacing along the axis of rotation of the rotary body and an annular yoke of ferromagnetic material interposed between each two adjacent magnets. Each of the magnets is magnetized to opposite polarities at its respective opposite ends in the direction of the axis of rotation, each two adjacent magnets being magnetized to the same polarity at their ends opposed to each other with the yoke interposed therebetween.

摘要： A system that includes an elongate cylindrical vehicle operable to travel along a similarly-shaped, trough-like guideway. At stations along the guideway, the vehicle is supported by wheels, but between stations it levitates at about 25 centimeters above the inside guideway surface. Levitation of the moving vehicle is effected by interaction between magnetic dipole fields provided by superconducting coils or permanent magnets disposed over substantially the whole lower surface area of the vehicle and a pair of spaced conducting strips located on the guideway inner surface and oriented parallel to the longitudinal axis of the guideway throughout its length. The vehicle is free to rotate or pivot about its longitudinal axis and this, coupled with the very resilient support over its entire length, permits it to travel at 200 kilometers per hour and beyond with minimum discomfort to passengers being transported. The magnetic dipole fields must be of the order of 1,000 to 3,000 gauss at a distance of 25 centimeters from the vehicle to give the support necessary to maintain the 25 centimeter clearance. The necessary propelling force is supplied by a polyphase winding which is disposed in the lower portion of the guideway between the conducting strips; the winding produces a traveling-wave magnetic field that interacts with the magnetic dipole fields. Between stations synchronous operation is accomplished by employing a.c. power input with a cycloconverter, i.e., an a-c to a-c converter, to reduce the input frequency to an appropriate ratio. Acceleration and deceleration of the vehicle is accomplished by varying the frequency of the cycloconverter to provide synchronous interaction between the magnetic field of the winding and the magnetic dipole fields of the superconducting coils as the vehicle accelerates. Provision is made for switching vehicles, and a novel method of guideway fabrication is disclosed.

摘要： A vehicle-suspension type of permanent magnet-levitation transportation system has an elevated track structure defining a bed with a ferromagnetic levitation track on the underside thereof and a spaced parallel control track composed of ceramic magnetic material having transverse polarity orientation also running on the underside of the bed. A vehicle for traveling along the track has a series of spaced cobalt-rare earth levitation magnets positioned under the ferromagnetic track and a series of spaced cobalt-rare earth control magnets positioned under the control track in magnetic repulsion mode with the ceramic magnets. In levitated position the attraction of the levitation magnets for the ferromagnetic track is balanced by the repulsion between the control magnets and the ceramic track. Hydraulic, mechanical and electromagnetic means for positioning the levitation and control magnets in proper vertical relationship to maintain levitation of the vehicle are described.

摘要： A high-speed terrestrial vehicle that is magnetically levitated by means of magnets which are used to induce eddy currents in a continuous electrically conductive nonferromagnetic track to produce magnetic images that repel the inducing magnet to provide primary lift for the vehicle. The magnets are arranged so that adjacent ones have their fields in opposite directions and the magnets are spaced apart a distance that provides a secondary lift between each magnet and the adjacent magnet's image, the secondary lift being maximized by optimal spacing of the magnets.

摘要： The invention relates to a magnetic bearing assembly of a rotor in a stator, with at least one magnetic bearing (1) comprising a stator part (2) and a rotor part (3) arranged coaxially thereto in the operating position without contacting the stator part. The bearing effective area of the rotor part is formed by a radial exciting system (6) having a permanent magnet (4), while the stator part (2) comprises a high-temperature superconductor concentrically surrounding the radial exciting system (6) while maintaining an annular air gap (10). For increasing the specific rigidity of such a bearing, it is proposed according to the invention that the high-temperature superconductor is divided in at least two HTSC partial shells (7, 8) which, after the transition into the superconducting state, can be displaced against one another by an actuator (12) in the radial direction from a position in the hot state of the bearing, in which each HTSC partial shell (7′, 8′) has a first radial spacing (k) from the radial exciting system (6), into a working position with a second, smaller radial distance (operating gap (0)from the radial exciting system (6).

摘要： A magnetic thrust bearing (110) comprises a magnet (112) mounted on a shaft (114) and a plurality of equi-angularly spaced superconductors (116) mounted on a static structure (118). Each superconductor (116) is mounted onto the static structure (118) by a parallel hinge strip (120) which allows the superconductor (116) to move radially relative to the axis of rotation of the shaft (114). The radial movement of the superconductors (116) changes the cross-sectional area of the magnetic field between the magnet and the superconductors (116) and this changes the stiffness of the magnetic bearing (110). The superconductors (116) move radially due to the pivoting of the parallel hinge strips (120) due to changes in the loads acting on the magnetic bearing (110). It is possible to detect movement of the shaft and to actively move the superconductors to control the stiffness of the magnetic bearing and to control the clearance in the magnetic bearing as in FIG. 5.
