This paper proposes a novel hybrid suspension electromagnet for application in the middle-low speed maglev train. Its configuration and working principle are introduced. Mathematical models of the suspension force and guidance force are established accurately by equivalent magnetic circuit method (EMCM), from which the relationships of suspension force-control current-suspension gap and guidance force-guidance displacement are derived. Finite element method (FEM) is also applied to analyze the performances and characteristics of the novel hybrid suspension electromagnet. The analysis results are in good agreement with those calculated by EMCM, which is helpful in designing and optimizing the suspension system. The comparisons are made between the performances of the novel and the traditional electromagnets. The contrast results indicate that the proposed hybrid suspension electromagnet possesses better performances compared to the traditional structure, especially the little control current and the low suspension power loss.
