  • Patent number: 10917027
    Abstract: Method for transferring a transport unit of a long stator linear motor at a transfer position from a first transport section to a second transport section. On each side of the transport unit, excitation magnets are arranged to interact with driving coils, and on both sides of the transport unit, excitation-magnetic lateral forces are acting on the transport unit by an interaction of the excitation magnets with ferromagnetic components of the guide structure. Method includes supplying on at least one side of the transport unit a stator current n a driving coil to generate a lateral force-forming electromagnetic force that acts on the transport unit, so that a resulting lateral force, as a sum of the acting excitation-magnetic lateral force and of the lateral force-forming electromagnetic force, on each side of the transport unit is different to produce a steering effect on the transport unit at the transfer position.

Switch adjustment is effected by displacement of the load-bearing frame along the rail by means of the drive mechanism and a thus-effected flexing of the girder. The girder, the load-bearing frame and the drive mechanism form a solidly joined-together structural unit which as a whole is located displaceably in the travel direction (x) relative to the rail and the rack.

    Abstract: A switch is used, at the divergent zone, to cause the vehicle bogie to follow one path or the other in the guideway. This is accomplished by substituting an attracting magnetic array on the side that the vehicle bogie is desired to follow. The switch may operate without moving parts, so there is no inertial penalty to limit operational frequency. The switch is designed to fail gracefully in the absence of activation power or control signals. Further, the switch is designed to ensure that there would be no derailment or dropping of a vehicle.

  • Patent number: 7757609
    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 and cost of materials, while maximizing lift force. The vehicle is stabilized in the lateral and yaw directions with feedback controlled lateral control coils that interact with the permanent magnet rails on the guideway. A track switching structure employs permanent magnet rails that gradually widen along a segment of track and separate into two identical diverging rails. Feedback controlled lateral control coils in a moving vehicle stabilize that vehicle over one or the other pairs of diverging rails, as directed by a control computer, thereby causing the vehicle to continue along one path or the other, with no moving or active elements required in the track.

  • Patent number: 7617779
    Abstract: This disclosure describes an electromagnetic system for efficient propulsion, suspension, and guidance. The track is inexpensive totally passive steel. This linear form of the D.C. motor provides traction motor characteristics without physical contact, The moveable element (vehicle) comprises both the integrated armature and field magnet flux source which induces magnetizing flux into pairs of rails each energizing a set of interdigitated poles of alternating polarity in the track against which its own armature conductors interact for thrust and braking. This source of magnetic flux requires no power and provides passive suspension at any speed and, with control, guidance. The permanent magnet and control flux in common airgaps multiply the effectiveness of lateral control for magnetic stabilization and to restrain external forces.

    Abstract: The invention relates to a line-changing device for the tracks (1, 2) of a magnetic levitation train. The tracks (1, 2) are formed by track supports arranged one after the other and the lines are changed by means of a rail joint between the tracks (1, 2). To connect the tracks a track support configured as a bendable support (5) is positioned along each track which bendable support can be bent to establish a connection between the tracks (1, 2). In its bent state each bendable support can be positioned in relation to the other bendable support (5). Along each track (1, 2) a track support situated next to the bendable support (5) is configured as a connecting support (6), which when the rail joint is established can be moved out of the clearance gauge of the train. The invention consists in the fact that the connecting supports (6) can be moved without deformation.
