Comparative Analysis of the Performance of High-speed Maglev Trains Based on Normal Conductive and Superconductive Magnetic Poles

Because of its non-sticking and high-speed characteristics, high-speed maglev trains have become a new non-contact transportation mode mainly studied in recent years. In this paper, the finite element model of the normally conducting linear motor is first established based on the structure of the normal conductive test prototype, and after calculation, it is compared with the experimental data for verification. Secondly, a three-dimensional global model of superconducting linear synchronous motor for maglev trains is established, and the three-dimensional global model is equivalent to the two-dimensional numerical calculation model considering the transverse edge effect, at 50km / h and 40km / h, the normal conducting and superconducting linear motor are compared. Finally, the electromagnetic output performance of normal conductivity and superconductivity under 600km/h conditions is compared and analyzed, and the output characteristics of the two are studied when the excitation current changes.
