Abstract: Aiming at the problems of the high energy consumption, easy heating generation and suction phenomenon of traditional electromagnetic levitation technology, a one-way control anti-suction hybrid suspension electromagnet based on magnetic focusing effect was proposed. In the study, the guiding force and suspension force of the hybrid suspension electromagnet were deduced mathematically and the mathematical model of the designed electromagnet was established. The correctness of the mathematical model and the superiority of the designed electromagnet structure were verified by Maxwell finite element simulation. The simulation results show that the energy consumption of the electromagnet structure was 30% lower than that of pure electromagnetic and the current unidirectional control and anti-suction strategy were realized. The new hybrid suspension electromagnet meets the application requirements of medium and low speed maglev trains in terms of suspension stability and safety, providing an innovative solution for the development of maglev technology.
