In this paper, a novel DC hybrid magnetic bearing with crossed poles is proposed, which is used to simplify the structure, obtain the maximum bearing capacity and realize the decoupling in radial 2-DOF. The suspension poles in the Y direction are designed as the crossed poles to realize the full symmetric radial design. Firstly, the configuration and suspension principle are introduced. Secondly, the mathematical models of radial suspension force are deduced. Finally, the three-dimensional finite element analysis is carried out. The analytical results agree well with the numerical calculation results.
