JR-Maglev, MLX01, at Yamanashi

JR-Maglev, MLX01 (X means Experimental), is a magnetic levitation train system developed by the Japan Railway Technical Reasearch Institute (association of Japan Railway Group), composed of maximum 5 cars to run on the Yamanashi Maglev Test Line. On December 2, 2003, a three-car train set attained a maximum speed of 581 km/h (world speeed record for maglev trains) in a manned vehicle run.

Magnetic levitation trains consist of a levitation system, a guide system, and a driving system.

Levitation

JR-Maglev Levitation system is offered by a Electrodynamic Suspension System (or EDS). Moving magnetic fields create a reactive force which is produced in a conducter by its magnetic field effect. The force holds up the train. The maglev-trains have Superconductivity Magnetic Coils, and the guide ways have levitation coils.

When the trains run at high speed, Levitation Coils on guide way get rebounding forces by the Superconductivity Magnetic Coils of the trains.

EDS has advance that is larger gaps than EMS, But EDS need supported wheels which are employed in low speeded running.Because EDS can't get large force in lower speeded (150km/h or less in JR-Maglev).

Guide

Levitation coils which are located on the guide way generate guide force.

Driving

JR-Maglev is driven by a Liner Synchronous Motor (which called LSM) System. This system needs to suply power to the coils at guide-way.

Experimental lines in Yamanashi Prefecture

JR-Maglev at Yamanashi

Yamanashi Experiment Lines are facilities that currently have a practical use. It includes about 18.4km of rail (including 16.0km of tunnels).

History

  • 1962 – Initial technology research was started.
  • 1977 – Miyazaki Prefecture began applying the technology to rail transport.
  • 1979 – Experimental train reached a speed of 517 km/h (with no passengers).
  • 1987 – Reached a speed of 400.8 km/h with passengers.
  • 1997 – The experiment run was started at Yamanachi tracks (MLX01) on April. In December, it reached a speed of 531 km/h with passengers.
  • 2003 – Reached a speed of 581 km/h with passengers (its record)!
