Numerical simulation study of power-frequency exposure to driving windings of electromagnetic suspension high-speed maglev trains.

This article focuses on assessing the electromagnetic exposure risk to passengers inside electromagnetic suspension (EMS) high-speed maglev trains caused by 50 Hz three-phase symmetrical currents in the long stator drive windings. Using numerical simulations with finite element software, simplified human body models, and train compartment models, the study calculates magnetic flux density and induced electric field strengths at various passenger positions, particularly near windows where electromagnetic leakage is more pronounced. Results show that although passengers near windows experience higher electromagnetic exposure, all measured values remain well below the safety limits established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) 2010 guidelines, indicating no short-term acute health risk. The study highlights the importance of considering electromagnetic exposure dosimetry in maglev train systems and suggests future research incorporate more detailed anatomical models and experimental measurements.
