Inductrack (original) (raw)
Inductrack war ein experimentelles Magnetschwebebahn-System mit Permanentmagneten in Halbach-Anordnung. Wie bei anderen elektrodynamischen Schwebesystemen (EDS) induziert die Bewegung der Magnete Ströme im Gleiskörper, deren Magnetfeld die Abstoßung bewirkt. Ohne Regelungssystem für die Levitation sollte es ausfallsicherer und weniger wartungsintensiv sein als die übrigen Magnetschwebesysteme.

(de) Inductrack is a passive, fail-safe electrodynamic magnetic levitation system, using only unpowered loops of wire in the track and perslide magnets (arranged into Halbach arrays) on the vehicle to achieve magnetic levitation. The track can be in one of two configurations, a "ladder track" and a "laminated track". The ladder track is made of unpowered Litz wire cables, and the laminated track is made out of stacked copper or aluminium sheets. There are three designs: Inductrack I, which is optimized for high speed operation, Inductrack II, which is more efficient at lower speeds, and Inductrack III, which is intended for heavy loads at low speed. Inductrack (or Inductrak) was invented by a team of scientists at Lawrence Livermore National Laboratory in California, headed by physicist Richard F. Post, for use in maglev trains, based on technology used to levitate flywheels. At constant velocity, power is required only to push the train forward against air and electromagnetic drag. Above a minimum speed, as the velocity of the train increases, the levitation gap, lift force and power used are largely constant. The system can lift 50 times the magnet weight. (en) Inductrack è una tipologia di treno a levitazione magnetica completamente passivo. Il sistema si basa su anelli di fili non alimentati innestati nel tracciato e su magneti permanenti (in configurazione array Halbach) utilizzati per far levitare il treno. Inductrack venne inventato nei Lawrence Livermore National Laboratory dal fisico . L'unica energia richiesta è quella utilizzata per muovere il treno. Il movimento del treno incrementa la forza levitante indotta nei fili. Sono utilizzati magneti permanenti al neodimio ferro boro; a basse velocità la forza di levitazione generata è sufficiente a sollevare 50 volte il peso dei magneti. Una variante utilizza due Array Halbach per raddoppiare il campo magnetico senza incrementare sostanzialmente il peso ed ottenendo una minor richiesta di energia a velocità ridotte. Molte proposte di Maglev sono basate su Inductrak Si cerca di utilizzare questa tecnologia per facilitare il lancio dei razzi spaziali.
