Abstract
A magnetic levitation transport system includes magnetic levitation vehicles each driven by a linear motor to run along a track. Induction lines extend through predetermined blocks of the running track to transmit a high frequency sine-wave current. Each vehicle includes electromagnets to attract levitating magnetic members extending along the running track, a pickup coil resonant with a frequency of the induction lines to generate an electromotive force, and a battery chargeable by the pickup coil. The electromagnets receive power from the pickup coil and/or the battery.
