Inductrack

Inductrack was an experimental magnetic levitation train system with permanent magnets in a Halbach arrangement . As with other electrodynamic levitation systems (EDS), the movement of the magnets induces currents in the track, whose magnetic field causes the repulsion. Without a control system for the levitation, it should be more fail-safe and less maintenance-intensive than the other magnetic levitation systems.

history

In May 1998, researchers at the Lawrence Livermore National Laboratory in Livermore ( California ), headed by Richard Post, presented the “Inductrack” magnetic levitation system as a by-product of the flywheel energy storage project, which is primarily operated . General Atomics in San Diego built a 120 m long Inductrack test track with linear motor drive with funding from the US Federal Transportation Authority (FTA of DOT ) with the goal of “urban transport system”. In October 2004 the first tests were carried out with an 8000 kg vehicle chassis to check the data acquisition and control electronics. Due to the short distance, the speed was limited to 10 m / s. It could be shown that the levitation and propulsion principle work and that the test vehicle levitates from a speed of 10 m / s. A National Geographic video report shows driving tests with the Inductrack test vehicle. For 2008 the construction of a 7.4 km long demonstration route on the grounds of the California University of Pennsylvania (CUP) was planned. It was not realized. Post died in 2015.
