Nowadays, with the development of the times, maglev technology is becoming more and more mature. The author of this paper focuses on the development and technology of maglev trains, introduces the development process of maglev trains in China, Japan, Germany and other countries, and describes the similarities and differences in the technology of maglev trains in each country. In the following, three types of maglev technologies are illustrated: electromagnetic levitation, electric levitation, and high-temperature superconducting maglev. The three technologies have a certain intersection in principle and use the magnetic force between the track and the train to levy. At the same time, the author introduces the different applications of each technology. In the latter part of the article, the author briefly introduced another application of magnetic suspension - magnetic suspension bearing and described its application in many fields. In the end, the author puts forward the existing problems of maglev trains and the necessity of solving them according to his point of view.
