What does EDS stand for when discussing maglev trains?
Electrodynamic suspension (EDS) uses superconducting electromagnets or strong permanent magnets that create a magnetic field, which induces currents in nearby metallic conductors when there is relative movement, which pushes and pulls the train towards the designed levitation position on the guide way.
How are maglev trains propelled?
The front corners have magnets with north poles facing out, and the back corners have magnets with south poles outward. Electrifying the propulsion loops generates magnetic fields that both pull the train forward from the front and push it forward from behind. Maglev trains are “driven” by the powered guideway.
What is a maglev train track called?
The Maglev Track. The magnetized coil running along the track, called a guideway, repels the large magnets on the train’s undercarriage, allowing the train to levitate between 0.39 and 3.93 inches (1 to 10 centimeters) above the guideway [source: Boslaugh].
How is a maglev train propelled by the magnetic field?
The detailed working of MAGLEV train is shown in the figure below. The train is propelled by the changing in magnetic fields. As soon as the train starts to move, the magnetic field changes sections by switching method and thus the train is again pulled forward. The whole guide way is run by electromagnets so as to provide the magnetic effect.
What are the basics of magnetic levitated trains?
The Basics of Magnetic Levitated Trains (Maglev) Magnetic levitation (maglev) is a relatively new transportation technology in which non-contacting vehicles travel safely at speeds of 250 to 300 miles-per-hour or higher while suspended, guided, and propelled above a guideway by magnetic fields. The guideway is the physical structure along which
Which is the only high speed maglev train in the world?
The TR07 has been tested extensively in Emsland, Germany, and is the only high-speed maglev system in the world ready for revenue service. The TR07 is planned for implementation in Orlando, Florida. The EDS concept under development in Japan uses a superconducting magnet system.
Why are maglev trains less polluting than cars?
In 1990, less than 5 percent of the Nation’s electricity was derived from petroleum whereas the petroleum used by both the air and automobile modes comes primarily from foreign sources. Maglev is less polluting – with respect to air and auto, again because of being electrically powered.
