Maglev Trains by: lucas tafara


Today I will talk to you about maglev trains. I will tell you, what they are, how they work, where do they use them, the difference between EMS ( Electromagnetic suspension) and EDS (Electrodynamic suspension) try to learn something new and enjoy.


A maglev train is a train that uses maglev technology. If you don't know what maglev technology is or what maglev means, I will answer both of those questions in my next statement. The meaning of the word maglev is magnetic levitation. Now let me explain the maglev system "A transportation system in which trains glide above a track, supported by magnetic repulsion and propelled by a linear motor (which are basically electric motors)." So to summarize what a maglev train is it is a train that uses electromagnets so that the train floats 0.39 inches to 3.93 inches of the ground and is frictionless so that the train can move faster. The fastest maglev train's top speed is 600kph.


There are three major components to a maglev train. 1) A large electrical power source. 2) Magnetic coils that line the inside of the guideway or track. 3) Large magnets on the train. These three major components work in unison with a couple other variables to make the train function. First the electric source turns on, then the electromagnets on both the train and the guideway are turned on which creates a magnetic field. Since the magnets on the guideway are constantly changing polarization so the magnets on the train are getting attracted then repelled by the same magnet which causes the forward motion (it will go more into depth about it in the video) so the faster the polarization of the electromagnetic coils on the guideway changes the faster the train travels.

EDS maglev trains vs EMS maglev trains

The difference between EDS maglev trains and EMS is that the EDS system uses super-cooled super conductive electromagnets that can still can conduct electricity and create a magnetic field even when the power source is turned off. The EMS system just uses standard electromagnetic that shut off after the power source in turned off.


Maglev trains are made in Germany, Japan, Spain, France, China and South Korea. The first commerical maglev train is open to the public was in China in 2004.

Fun Facts About Maglev Trains

1. Maglev trains can cover a distance of 30.5km in 8min. 2. Derailment is almost impossible on a maglev guideway 3. Maglev trains produce no air pollution because no fuel is being burned because a lot of them run on electricity.
