Maglev train isa new type of rail transportation, compared with the general wheel rail train, which has the advantages oflow noise, low energyconsumption, no pollution, safety, and high efficiency. So it is considered to be a promising new means of transport. As we know, magnets of the same polarity willrepel each other, while those of different polarity will attract each other. Maglevtrain takes the theory into practice to hold thevehicle, and converts electrical energy to promote force to push the new fifthgeneration transportation train forward by using linearmotion actuator. In a word, thecurrent situation of the development of Maglev train is worth studying.
