  • Patent number: 4015540
    Abstract: An electromagnetic transportation system for a vehicle which is adapted to travel along the inside of a tube. The system includes a series of electrical coils about the periphery of the tube which are connected to a three-phase alternating current supply. The vehicle is a capsule adapted to move within the tube and is essentially a ferro-magnetic container. The coils are energized by the three-phase alternating current supply to produce bundles of magnetic energy moving in one direction and the capsule is propelled by the magnetic energy in the same direction. The capsule also includes spaced coil members in order to utilize both radially and axially directed magnetic energy to propel the capsule in the tube and includes means to create a plurality of magnetic pole faces to increase the efficiency of propulsion.
