The propulsion generated by the linear induction motor travels on the track. The electrified suspension electromagnet on the suspension frame of the normally-conducting high-speed maglev train and the long stator coil on the track mutually attract each other to provide suspension force for the train, suck the train upwards, and ensure a stable suspension gap by controlling suspension exciting current. The suspension clearance between the electromagnet and the track is generally controlled to be 8-12 mm.
The electrified guide electromagnet on the suspension frame interacts with the guide plate on the side surface of the track to provide a guide force, so that a certain lateral distance is kept between the vehicle body and the track, and the non-contact guide in the horizontal direction is realized. The high-speed maglev train is driven by a non-vehicle-mounted power device, namely a long stator Linear Synchronous Motor (LSM), a suspension electromagnet coil is arranged at the lower part of a vehicle suspension frame, a long stator coil is arranged on a track, and when the long stator coil arranged along the line direction provides three-phase frequency modulation and amplitude modulation power, the train is pushed to advance under the action of electromagnetic induction, so that the complete non-contact traction and braking of the train in a suspension state are realized.
