Patent ID: 7484462

Claim:
A permanent magnetic levitation apparatus, comprising: a permanent magnetic track unit including: a ferromagnetic track trough which is open at a top thereof and has a first side wall and a second wall opposed to each other, a track permanent magnet disposed in the track trough, in which a N pole of the track permanent magnet is positioned at the open top of the track trough, first and second non-ferromagnetic spacers which are disposed between the first and second side walls of the track trough and the track permanent magnet, respectively, a permanent magnetic levitation wing unit on a magnetic levitation vehicle, the permanent magnetic levitation wing being levitated over the permanent magnetic track unit and including: a ferromagnetic wing trough which is open at a bottom thereof and has a first side wall and a second side wall opposed to each other, a wing permanent magnet disposed in the wing trough and correspond to the track permanent magnet, in which a N pole of the wing permanent magnet is positioned at the open bottom of the wing trough so as to face the N pole of the track permanent magnet in the track trough, and the track permanent magnet has a width substantially equal to that of the wing permanent magnet, third and fourth non-ferromagnetic spacers which are disposed between the first and second side walls of the wing trough and the wing permanent magnet respectively, wherein magnetic force lines of approximately parabola shape are generated from the wing permanent magnet to the first and second side walls of the wing trough, and from the track permanent magnet to the first and second side walls of the track trough, respectively.
