Modeling simulation and experiments for the hybrid maglev system

XU Shao-hui,XU Zheng-guo,JIN Neng-qiang,SHI Li-ming(Institute of Electrical Engineering,Chinese Academy of Sciences,Beijing 100080,China)  
To lower the abundant power loss of the electromagnetic suspension system(EMS),which does not take part in the propulsion of the vehicle,permanent magnets are added into the levitation system to construct hybrid levitation system,where permanent magnets can support a part of load and electromagnetic system can regulate rapidly to realize steady suspension.Mathematical model for the hybrid levitation system is built based on the equivalent method,and the levitation forces of the hybrid levitation system are calculated with the proposed model,which are much bigger than those of the pure electromagnetic system.The experimental results are consistent with the calculated ones,which proves the suggested model of the hybrid levitation system.The conclusion is drawn that the hybrid levitation superiority that only small currents are needed and low power loss is consumed in the hybrid levitation system.
