    摘要: In a suspended track bound propulsion vehicle driven by a synchronous linear motor comprising an exciter winding and a traveling field winding vertical oscillations are attenuated by supplying to the synchronous linear motor with an AC voltage variable in amplitude and phase with variations obtained through an adjustable controlled static converter responsive to a control signal developed in a damping control having an input from measuring means which output a variable which is proportional to the vertical oscillations of the propulsion vehicle.

    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 (7null, 8null) 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: An electromagnetic railgun launcher and armature. The armature is made from superconducting material and is levitated between the rails of the launcher by the Meissner effect. The Meissner effect is created by cooling the armature and subjecting it to a magnetic field. The armature configuration has a closed loop topology and defines two planes - one plane coincides with the plane of the rails; the other plane is oblique to the first. The armature configuration, when placed between the rails receives an unbalanced Lorentz force which accelerates the armature.

    摘要: A linear magnetic bearing provides magnetic support by means of permanent magnets and control by means of electromagnets and an electronic control system such that virtually zero power is required to maintain the bearing in suspension. Persisting net force producing electric energization of the electromagnets resulting from displacement of the bearing causes the energization to be augmented to reposition the bearing to an oppositely displaced position of substantial equilibrium with minimized net force producing electric energization of the electromagnets. The linear magnetic bearing is effectively utilized in one application to significantly reduce the power requirements for magnetic levitation vehicles.

    摘要: A superconducting bearing device for supporting a rotary shaft (rotary body) 2 in a noncontact state for rotation at a high speed. A superconducting bearing 4 for supporting the rotary shaft 2 in a noncontact state relative to a housing 1 comprises permanent magnets 14 mounted on the rotary shaft 2, and Type II superconductors 17 attached to the housing 1 and opposed to the magnets as vertically spaced apart therefrom. A mechanical catcher bearing 21 comprising a thrust ball bearing is disposed between the housing 1 and the rotary shaft 2 at opposed portions thereof. An initial position determining mechanism is provided for lifting a bearing ring 23 of the catcher bearing 21 on the housing 1 to position the housing 1 and the rotary shaft 2 in place relative to each other, whereby the superconductors 17 and the permanent magnets 14 on the shaft 2 can be positioned in place relative to each other. The superconducting bearing 4 can be operated efficiently by suitably determining the relative position. The catcher bearing 21 prevents damage to the rotary shaft 2 and parts therearound when the superconductors 17 of the bearing 4 become normally conductive.

    摘要: A superconducting bearing device includes a permanent magnet on a rotor, with a superconductor placed opposite the magnet. Flux trapped in the superconductor during cooling helps to stabilize the rotor. More specifically, the permanent magnet is mounted on the rotor so that, as the rotor rotates, its rotation does not alter the magnetic flux distribution around the axis of rotation of the rotor. The superconductor permits penetration of the magnetic flux from the magnet, being spaced from the magnet by a distance that permits a predetermined quantity of the magnetic flux to penetrate it, while not permitting rotation of the rotor to alter the distribution of the penetrating magnetic flux.
