    Abstract: The invention relates to an arrangement for operating a magnetically levitated vehicle by means of an arrangement having at least one long-stator linear motor. The linear motors are sub-divided, longitudinally of a track, into individual motor regions (A) in each of which only one vehicle (7) is able to travel at a time. To make possible different frequencies of service for the vehicles (7), i.e. different intervals between the vehicles (7), the region boundaries (B) between at least two motor regions (A1, A2) which follow one another in the direction of travel are arranged to be variable.

  • Patent number: 7096794
    Abstract: A simple permanent-magnet-excited maglev geometry provides levitation forces and is stable against vertical displacements from equilibrium but is unstable against horizontal displacements. An Inductrack system is then used in conjunction with this system to effect stabilization against horizontal displacements and to provide centering forces to overcome centrifugal forces when the vehicle is traversing curved sections of a track or when any other transient horizontal force is present. In some proposed embodiments, the Inductrack track elements are also employed as the stator of a linear induction-motor drive and braking system.

  • Publication number: 20040182275
    Abstract: Functional elements in a railway track are supported on structural elements supported on the ground. Electromagnetic circuitry on a railroad operates in conjunction with the functional elements to provide electromagnetic levitation and drive for the railroad. The functional elements are fabricated in relatively small sections, approximately six meters in length. The structural elements, which support the functional elements and the functional elements are fabricated separately and shipped separately to the site of the railway track where they are assembled together to form the support for the railroad.

  • Patent number: 6758146
    Abstract: A magnet configuration comprising a pair of Halbach arrays magnetically and structurally connected together are positioned with respect to each other so that a first component of their fields substantially cancels at a first plane between them, and a second component of their fields substantially adds at this first plane. A track is located between the pair of Halbach arrays and a propulsion mechanism is provided for moving the pair of Halbach arrays along the track. When the pair of Halbach arrays move along the track and the track is not located at the first plane, a current is induced in the windings and a restoring force is exerted on the pair of Halbach arrays.

  • Patent number: 6753666
    Abstract: An apparatus for operating a magnet vehicle, especially a magnetically levitated vehicle. The apparatus includes a long stator linear motor with at least one long stator winding laid along a track and at least one exciter arrangement cooperating with this winding and mounted on the vehicle. The long stator winding is divided into winding sections (5.4, 26.4) following one another, which each have a greater length than the exciter arrangement. At least two section cables serve to supply the winding sections with electric power and switch devices serve to connect the winding sections (5.4, 26.4) sequentially to a section cable each in correspondence with the progression of the vehicle. In accordance with the invention the winding sections (5.4, 26.

  • Patent number: 6684794
    Abstract: A magnetically levitated transportation system employs permanent magnet rails along a guideway that interact with permanent magnets on a vehicle. The rails are optimized to reduce magnetic mass, while maximizing lift force. In one example, the arrays are composed of arrays of magnets having rotating magnetizations, such as Halbach arrays. In another example, the arrays are cup-shaped to provide stronger magnetic field forces in the central portion of the array, relative to the lateral portion of the array. The vehicle may be stabilized in the lateral and yaw directions with feedback controlled lateral control coils that interact with the permanent magnet rails on the guideway. Vertical, pitch and roll motions may be controlled or damped with eddy-current damper coils or plates or with active feedback control to control the coils.

    Abstract: A guideway for a magnetically levitated railway is described, having a longitudinal stator linear drive comprising at least two parallel stators. The guideway includes a plurality of supports (1) arranged along a given line and adapted to form straight and curved guideway sections and stator sections mounted on the supports (1), these sections being composed of straight stator end packs (6a, f; 7a, f) and likewise straight middle stator packs (6b-3; 7b-e) arranged therebetween, the packs in the region of the curved guideway sections being laid in the manner of polygonal trains to form outer and inner stator sections (6, 7) and being separated from one another by gaps (23, 24). The stator end packs (6a,f; 7a,f) and the middle stator packs (6b-3; 7b-e) have a predetermined tooth/groove pitch (16) with reference to a conceptual space curve (2) and different “ideal” lengths which differ from one another by fractions of a tooth/groove pitch (16).
