A study was conducted on the mechanical and electromagnetic characteristics of the suspension electromagnet in maglev trains.A three-dimensional finite element analysis and calculation model of the suspension electromagnet was established,and the structure and electrical parameters affecting the electromagnetic attraction of the suspension electromagnet were analyzed.A calculation formula for the electromagnetic attraction of the suspension electromagnet applicable to engineering design was proposed,and an optimized small electromagnet scheme was proposed with the maglev car as the carrier and the goal of engineering miniaturization.The results indicate that the optimized suspension electromagnet can meet the requirements of engineering maglev vehicles,and there is no phenomenon of iron core magnetic saturation.
