Abstract:
Apparatus, systems and methods for levitating and moving objects are shown and described herein. The embodiments incorporate a track with lower rails having permanent magnets abutted against each other and aligned such that the upper surface of each of the lower rails has a uniform polarity; and the object with upper rails having permanent magnets aligned with the lower rails and oriented to oppose the polarity of the lower permanent magnets. Ferrous backing plates behind the lower rails and/or the upper rails may be incorporated. Embodiments may also incorporate a third rail of an electroconductive material, and a driving disc positioned near the third rail. Permanent magnets in the driving disc may be rotated with the driving disc in the presence of the third rail to accelerate the upper rails with respects to the lower rails.
Abstract:
A method of propelling a transit vehicle steered by a centerline electrified structural guidebeam located between two special steel load-bearing rollway beams, using magnetic linear motors suspended between each pair of steerable load-bearing wheels, to react inductively on the rollway beams, to produce tractive effort by four linear motors mounted under an eight wheel car.
Abstract:
A transport system has a pair of levitating rails, each of the levitating rails has a core with a plurality of coils extending circumferentially around each of the cores. The coils are perpendicular to the lengths of the levitating rails. Each of the levitating rails has an upper surface directly above the core. A vehicle has wheels that roll on the upper surfaces of the levitating rails in a nonlevitating position. The vehicle has a plurality of magnets that create magnetic fields that pass through the coils while the vehicle is moving along the levitating rails. The magnetic fields induce current, which in turn causes an opposing magnetic field that levitates the vehicle. A steering rail having a plurality of coils is mounted to at least one of the guideways. Permanent steering magnets are located on each side of the steering rail to magnetically steer the vehicle along the guideways.

A girder (11) for the production of a track system for track-bound vehicles, in particular a magnetic levitation train, includes a plurality of carriers. The girder has a heat-insulating cover (23) mounted at its upper side. The cover (23) rests on a floating bearing.
Abstract:
The present invention relates to a stability brake for absorbing parasitic vibrations of a stage moved to a working position in a motion system. The stability brake includes a motor coupled to a flexure plate through a translation system. The translation system translates horizontal motion of the motor into vertical motion of the flexure plate. The stability brake can be mounted to a stage in a motion system, such as a linear motion system. The stability brake is operative to absorb jitters and vibrations of the stage when the stage is moved to a working position in a motion system and held under servo at the working position.

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, 26.4) each comprise at least a first and a second winding section part (46a, 46b, 49a, 49b), wherein the first winding section part (46a, 49a) consists of first winding segments (51, 53) electrically conductively connected to one another and the second winding section part (46b, 49b) consists of second winding segments (52, 54) electrically conductively connected to one another. The segments have a smaller length than the exciter arrangement (6) and are so arranged one after the other in the direction of the track in a predetermined sequence that the winding sections (5.4, 26.4) always include in any arbitrary conceptual sector extending along the track and having a length corresponding to that of the exciter arrangement (6) at least a first and a second winding segment (51, 52 or 53, 54).
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 of windings 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.
Abstract:
A method is provided for controlling operation of a vehicle on a guideway system, wherein the vehicle includes a first element of a linear induction motor and an alternate power source, and the guideway system has an acceleration section including a second element of the linear induction motor, and a computer control system. The method includes utilizing the second element in cooperation with the first element so as to accelerate the vehicle on the acceleration section of the guideway system, and providing speed instructions to the vehicle using the computer control system so as to cause the vehicle to use the alternate power source to maintain a desired cruising speed on a main section of the guideway system.
Abstract:
A monorail system for passenger and light freight transportation provides a support structure with an essentially planar top surface and a stabilizer guide rail having a vertical web portion supporting a head portion. The head guides a vehicle along the top surface while conductors secured to the web portion transmit electrical current to the vehicle through a current collector secured to the vehicle. A portion of the stabilizer guide rail may be flexible providing a simple, inexpensive device for switching the vehicle between a plurality of tracks. The system operates equally well with a variety of vehicle propulsion and suspension systems including electromechanical, magnetic levitation or linear electric motors. In addition, the system may be operated with a semi-maglev system, wherein the vehicle is partially supported by wheels and magnetic levitation.
