Abstract: In order to improve the eddy current effect, the five-coil structure is used in Changsha Maglev Express with a top speed of 160 km / h. However, during the operation on the track, there are issues of uneven current distribution and unstable suspension control. The reasons for the poor stability of the end electromagnet module suspension control was analyzed, an optimization scheme for the end electromagnet module was proposed, and the rationality of the optimized scheme was verified according to the running data of the train line.
