A novel design of electromagnetic levitation system for high-speed maglev train

Aim: To reduce the levitation energy consumption and alleviate the adverse effects caused by the over-heating of the electromagnet. Methods: The design and manufacturing of hybrid electromagnet are introduced firstly. Secondly, the modification of driving chopper module together with a levitation control strategy and the design of an adsorption-prevention module are presented in details. Thirdly, a complete two-carriage maglev train is upgraded with the proposed hybrid electromagnet, choppers, and adsorption modules. Finally, an experiment is performed on a 1.5 km high-speed maglev test line to prove the efficiency of the proposed system. Results: In this paper, a novel electromagnetic levitation system architecture and safety protection strategy for the high-speed maglev train are proposed. Conclusion: A novel design of electromagnetic levitation system for high-speed maglev train is designed and implemented.
