Tongmao Linear Motors: Successful operation test of our new type of magnetic levitation train. The maglev train is known as a “zero-height vehicle” due to its advantages of low noise, low loss, and easy maintenance due to its non-contact and friction-free bodywork. Today, new progress has been made in zero-height aircraft.

     The success of this operation test is a phased achievement of the state's “Thirteenth Five-Year” advanced rail transit key special project, which indicates that China has mastered the core key technologies of medium-speed maglev transportation and is of great significance to promoting the development of China’s maglev transportation technology. 

     For the first time in the world, the train adopts the “Long Stator Permanent Magnet Linear Synchronous Traction + Permanent Magnet Electromagnetic Hybrid Suspension” technology program, featuring low energy consumption, high traction efficiency, and convenient equipment replacement and maintenance. Through the optimization and upgrading of the traction and suspension systems, a series of key technological breakthroughs have been achieved in terms of modularity, light weight, and integration. Compared with the low-speed maglev traffic that China is now operating, the suspension power consumption is reduced by 20%. The efficiency increased by more than 10%, and the comprehensive technical performance reached the international advanced level.

     This new type of maglev train, which combines the advantages of high-speed and low-to-middle-speed maglev transportation, will provide a convenient and fast green rail vehicle for China, and is ideally suited to operate between urban agglomerations, between central cities and satellite cities, and in large cities. ,have a broad vision of application.

     The National University of Defense Technology is one of the first units of China to carry out maglev transportation technology research. After 40 years of breakthrough, it has mastered a series of core keys such as suspension guidance control, suspension sensors, positioning and velocity measurement, bogies, car-track coupling resonance, and overall system design and integration. technology.

     Tongmao linear motor types can be divided into structural types; unilateral flat type, double flat type, disc type, cylinder type (or called pipe type), etc.; according to the working principle can be divided into: DC, asynchronous, synchronous and Stepping and so on. The structure of the linear asynchronous motor mainly includes three parts: a stator, a mover, and a linear motion support wheel.

     When one mentions a linear motor, people first think of a magnetic levitation train. This is very natural, because maglev trains are outstanding examples of practical applications of linear motors. Why is a maglev train driven by a linear motor? Let's take a look. A linear motor is an electric drive that converts electrical energy directly into linear motion. It can save a large number of intermediate transmission mechanisms, speed up the system to reflect the speed, improve system accuracy, so it has been widely used.
