  • Patent number: 9683601
    Abstract: An electromagnetic actuator can exert a radial electromagnetic force on a body that is configured to rotate about a rotational axis. The actuator includes a radial control magnetic pole assembly that includes radial control poles adjacent to and spaced apart by air gaps from the body. The actuator includes a permanent magnet (PM) magnetized along the axis, having one pole in contact with an axial face of the assembly and located proximate to a lateral surface of the body. The PM is magnetically coupled to the body in a non-contact manner resulting in a bias magnetic flux in the air gaps. The actuator includes a control coil around the radial control poles located radially outwards from the PM. Electrical current in the coils generates control magnetic flux in air gaps. The non-uniform net magnetic flux distribution around the body results in a radial electromagnetic force exerted on the body.

  • Patent number: 8985030
    Abstract: Inductrack III configurations are suited for use in transporting heavy freight loads. Inductrack III addresses a problem associated with the cantilevered track of the Inductrack II configuration. The use of a cantilevered track could present mechanical design problems in attempting to achieve a strong enough track system such that it would be capable of supporting very heavy loads. In Inductrack III, the levitating portion of the track can be supported uniformly from below, as the levitating Halbach array used on the moving vehicle is a single-sided one, thus does not require the cantilevered track as employed in Inductrack II.

  • Patent number: 8333156
    Abstract: A method provides for the traction control of a maglev car on a maglev track. A levitation magnetic field is produced by supplying a levitation magnetic flux on the car side to at least two levitation magnets to produce a defined air gap between the maglev car and a reaction rail on the track side. A stator current is supplied to the stator to produce a propulsion force on the maglev track, the propulsion force acts upon the maglev car being determined by the magnetic coupling between the magnetic stator field and the magnetic levitation field. An oscillating movement of the maglev car in relation to the magnetic stator field is dampened by changing the magnetic coupling between the magnetic stator field and the magnetic levitation field on the car side. The levitation magnets are operated on the car side with at least two different individual levitation magnetic fluxes.

  • Patent number: 8248196
    Abstract: The invention relates to a magnet arrangement for magnetic levitation vehicles. Said arrangement comprises a magnetic back box and a plurality of magnetic poles that are connected to said back box and that have magnetic pole faces bordering on a common reference surface. According to the invention, the reference surface extends along an elastic line when the magnetic pole is in the unloaded state, said elastic line being inverse to the curvature of the surface that is obtained under a nominal load of the magnetic poles when the magnetic pole faces are in the unloaded state on a plane. The invention also relates to a method for producing said type of magnet arrangement.

  • Patent number: 8224509
    Abstract: A system for controlling movements of a vehicle along a guideway includes an array of targets that are mounted on the vehicle, and a series of wayside sensors that are mounted on the guideway. A signal processor monitors the passage of targets past appropriate sensors and uses resultant signals to derive parametric values that are characteristic of the vehicle's movements. The parametric values are then coordinated with a controller for the operation of a linear synchronous motor that propels the vehicle.

  • Patent number: 8201502
    Abstract: A magnet pole, for magnetically levitated vehicles, includes a core (10) and a winding provided with winding disks that are arranged axially on top of each other. Both of the disks contain conduction band sections (6a, 6b) that are wound counter to the direction of winding and in several layers about the core (10). The conduction band sections are connected together in an electrically conductive manner by means of a connection part (1) on the core (10) near ends. The connection part (1) is bent in an outward manner on lateral longitudinal edges that are parallel to each other thus forming a curved outlet (12a, 12b).

  • Patent number: 8171858
    Abstract: The networked guideway transit system uses materials and methods of constructing guideway elements. The materials and methods are designed to reduce the static weight, cost and physical size of the guideway structure. Installation cost is also significantly reduced by the modular nature of the guideway components, which can be manufactured in a controlled factory environment using mass production methods. As a result, the supporting structure of the guideway can be quickly erected and the modular blocks inserted with simple equipment. In addition, complex alignment procedures are not required. In particular, the guideway component includes motor coils having the shapes and configurations that facilitate the easy insertion of the guideway component without the need for interleaving coils in adjacent guideway components and without creating dead spots in the magnetic fields between guideway components.

  • Patent number: 8118266
    Abstract: An apparatus generates position signals to indicate the position of a rail-bound vehicle along a travel way throughout which travel way many markings are located. The apparatus includes at least one sensor located on the vehicle for scanning the markings and outputting signals and an evaluation unit that is connected to the sensor for generating the position signals by evaluating the signals generated by the sensor by scanning the markings. When the vehicle passes a marking, the sensor outputs a “marking present” signal and otherwise outputs a “marking absent” signal. The vehicle has a receiver of a navigation system that is connected to the evaluation unit and outputs current location signals.

  • Patent number: 8074579
    Abstract: A magnetically levitated transport system moves a suspended cargo such as passengers and freight. A linear motor uses a track stator about which a “rotor” moves linearly. Stator and rotor circuits interact electromagnetically to maintain a gap between the moving and fixed elements. Tractor coils are embedded within the track to produce thrust through electromotor action with magnets aboard the rotor. The rotor is configured in a triangular shape as is the track with opposing electromagnets positioned for creating mutual repulsion forces. A pulsed direct current in the stator circuit, derived from conventional alternating current taken from the power grid, is used to create an induced current in the rotor, which, in turn is used to energize rotor electromagnets.
