On August 11, the second-generation low- and medium-speed maglev train project was run in Changzhou, Jiangsu, and some media reporters experienced this process. It is reported that the reporter's most intuitive feeling is smooth and quiet. During operation, only a low humming sound is heard when power is applied.

 

In addition, on the train, the most commonly seen are black boxes, which are magnetic levitation controllers. Generally, a train's suspension control system consists of three parts: a displacement sensor, a suspension solenoid, and a suspension controller. The principle of a magnetic levitation train is to convert electrical energy into electromagnetic suction, and then rely on the controller to suspend the train. Finally, under the effect of electromagnetic induction, the train is pushed to perform linear motion. Among them, suspension and drive are the two core systems. A large number of sensors will detect the gap between the train and the track in real time to ensure that it is stable at a safe distance of 8mm.
