An electrodynamic suspension system levitates a platform or a transportation vehicle by an array of onboard superconducting electromagnetic coils forming a primary member overlying a secondary member on the guideway in a transverse flux orientation with respect to a plane of levitation of the moveable member above the secondary member on the guideway. The superconducting coils are energized by alternating current to produce an alternating field of magnetic flux. The frequency of the alternating current is selectable down to direct current. The frequency is selected to cause the vehicle to be levitated statically above the guideway. Once levitated the frequency is reduced as the speed of the vehicle increases along the guideway usually not in excess of 60 miles per hour. Passive electrically conductive plates form the secondary member to respond to the alternating field of magnetic flux and both guide and levitate the vehicle by inherently-stable repulsive induction action to maintain a controllable spaced relation between the guideway and the vehicle.
An electrodynamic suspension system including a moveable member for levitation relative to a foundation, said moveable member including at least one onboard superconducting electromagnetic coil forming a primary member overlying a secondary member on a foundation in a transverse flux orientation with respect to a of levitation of said moveable member above said secondary member on said foundation, said at least one superconducting coil being energized by a variable alternating current to produce an alternating field of magnetic flux, said foundation including passive electrically conductive means forming said secondary member responsive to said alternating field of magnetic flux which induces an alternating current in said secondary member to guide and levitate the moveable member by repulsive induction action to maintain a controllable spaced relation between the foundation and moveable member.
An electromagnetic transportation system including a vehicle including means having an array of onboard superconducting electro-magnetic coils forming a primary member arranged in a transverse flux orientation with respect to longitudinal orientation of vehicle motion, at least one of said superconducting coils being energized by a variable alternating current to produce an alternating field of magnetic flux, and a guideway including passive electrically conductive means forming a secondary member responsive to said alternating field of magnetic flux which induces an alternating current in said secondary member to either or both guide and levitate the vehicle by repulsive induction action at a spaced relation from the guideway independently of propulsive vehicle movement.
