Optimization of Long-Stator Synchronous Linear Motors for High-Speed Maglev Trains

The high-speed maglev train nowadays, with its advantages of contactless operation, high speed, rapid acceleration, low energy consumption, and environmental friendliness, has become the only commercially feasible high-speed maglev solution. Improvement in technology and expanding application scenarios make enhancing capacity and speed a crucial factor for high-speed maglev research. This paper was focused on the dynamic electromagnetic characteristics of a 600 km/h constant-flux high-speed maglev train. Through analytical solutions and finite element analysis, the key factors affecting levitation suspension force and propulsion force were explored. The design is optimized using a genetic algorithm and its performance is verified through finite element simulation. Upon comparison to the existing structure, significant improvements in suspension and propulsion forces are indicated by the results. valuable theoretical backing for enhancing the energy efficiency of high-speed maglev trains is offered by the discovery.
