ABSTRACT:
The invention relates to a magnetic unit having a plurality of groups of ceramic magnets arranged in a side-by-side relationship, each plurality being separated from an adjacent plurality by a malleable steel member to focus the lines of magnetic flux. Preferably, each of the ceramic magnets within a group is also separated by an interleaved sheet of malleable steel. Such a plurality of groups of ceramic magnets are secured together and to a supporting member through fastening members, and are separated from the support by a non-magnetic member, such as a non-ferrous plate. A second plurality of groups of ceramic magnets are positioned adjacent to a first plurality of such groups of ceramic magnets with opposite poles of the magnets facing each other so that the first and the second pluralities of such groups of magnetics attract one another. Those forces of attraction are used to cause levitation of a vehicle such as a train. A plurality of such groups of magnetic units are so arranged relative to a support member of a train and an adjacent track member. A hydraulic unit, which may be microprocessor controlled, is used to adjust the air gap between respective pairs of such units. A third main feature of the invention relates to the use of such units to provide a main component of a linear motor for propelling the train along the track.
