Abstract

A method and apparatus is capable of high-speed transportation of passengers and/or freight. Vehicles (22) are operated along a guideway (14) as a result of the interaction between vehicle lift, steering and propulsion apparatus, each of which includes coil assemblies that are mounted on the vehicle (22), and magnet assemblies mounted on the guideway (14). Vehicle propulsion is provided by the interaction of currents on the vehicle (22) with time-varying magnetic fields that are generated along the guideway (14). The coils and magnets interact in accordance with the magnitude of electric current passing through the coils and the strength of the magnets'"'"' fields, to give lift and directional control to the vehicle. The lift and steering magnets (92, 94, 120, 122) provide substantially uniform magnetic fields so that the interaction between the lift coils and lift magnets, and respectively between the steering coils and steering magnets is substantially independent of positioning of the corresponding coils (104, 106, 108, 124, 126, 128 and 103).

Claims

a vehicle guideway including means for generating first time-varying magnetic field waves, a plurality of lift magnets, and a plurality of steering magnets, said lift magnets and said steering magnets are formed of permanent magnets for generating a uniform magnetic field;

said lift magnets have a U-shape including a pair of parallel legs and a bottom perpendicular to said legs, said plurality of lift coils are positioned within said parallel legs whereby the interaction between said lift magnets and said lift coils is substantially independent of the location of said lift coils over said bottom,

said steering magnets have a U-shape including a pair of parallel legs and a bottom perpendicular to said legs, said plurality of steering coils are positioned within said parallel legs whereby the interaction between said steering magnets and said steering coils is independent of the location of said lift coils over said bottom, said parallel legs of said lift magnets are positioned 90°

with respect to said parallel legs of said steering magnets, and at least one of said steering magnets is positioned between said lift magnets,

a vehicle transportable along said guideway in spaced relation therefrom, said vehicle includes a first and second wing and a cabin positioned between said first and second wing, at least one of said plurality of lift coils is mounted on said first and second wings respectively and at least one of said plurality of steering coils is mounted on said first and second wings,

a plurality of conductors mounted on the vehicle wherein said conductors are interactive with said first magnetic field waves for propelling said vehicle along said guideway;

a plurality of lift coils attached to said vehicle and interactive with said lift magnets for lifting said vehicle in a vertical direction above said guideway, said coils receiving electric current;

a plurality of steering coils attached to said vehicle and interactive with said steering magnets for steering said vehicle in a horizontal direction above said guideway; and

means for supplying electric current to said steering coils, at least one of said steering magnets is positioned between said lift magnets,

wherein at least one of said plurality of steering coils is mounted above said vehicle and at least one of said plurality of steering coils is mounted below said vehicle so that said vehicle is transportable up to a guideway bank angle of 37°
