“Neither a wise man nor a brave man lies down on the tracks of history to wait for the train of the future to run over him,”- President Dwight D. Eisenhower. Maglev is a new type of train that uses magnets to levitate above the track and reduce friction. Maglev can go up to a speed of 310 mph (500 km/h) allowing people to travel on land much faster than before. The researcher will create a model Maglev and see which system, EMS or EDS, will result in better efficiency. Efficiency will be measured by the ratio of weight of train to the time to cross the track. If EMS weighs more but is faster while EDS weighs less but more to operate, than EMS should result in better efficiency because the train will weigh less.
How Maglev Works
Electromagnetic Suspension (EMS)
Electromagnets are magnets that can be turned on and off with electricity. There is a big power source, metal coils in the track and magnets under the carts. The Maglev does not have an engine but is propelled by magnets in the track, called a guideway. Magnets in the guideway, repel the magnets in the train causing it to levitate between 1 to 10 cm. The magnets in front of the train are turned to pull the train while the magnets behind the train push it. Since the train is levitating, the friction is taken away and can cause the train to go up to speeds up to 500 km/h (310 mph).
A German company called Transrapid uses Electrodynamic Suspension (EMS). The bottom of the train wraps around the track and levitating it at 1 cm. Transrapid has shown that this system can cause the train to go 300 mph with people on board.
Electrodynamic Suspension (EDS)
Japan uses a system called Electrodynamic Suspension (EDS). It uses super-cooled superconducting magnets that are cooled to a low temperature and conduct electricity better. They can still conduct after they have been shut off. The train levitates 4 inches off the ground and needs rubber wheels to make the train move until it starts levitating at 62 mph. This can be an advantage because if there is a power failure, the train while be able to slow down and work on the wheels. This track is called the Inductrack. Inductrack 1 and Inductrack 2 are two types of this track. Inductrack 1 is used to go at faster speeds, while Inductrack 2 is used for slower speeds. The German company Transrapid, has a back up battery power supply if there is a power failure. The Japanese system costs even more because they use a coolant on the magnets to cause them to work better. Maglev uses magnets to raise the passengers up to speeds of 300 mph. Since the train uses magnets to raise itself above the guideway, it has no contact with the track and reducing friction. Long-stator is one of three propulsion systems. It costs the most to install, but costs less to operate and seems to be the most picked choice. Short-stator is the second system and costs less to install but costs more to operate due to the fact that there is more weight on the train....
