In this paper, a five-degree-of-freedom (5-DOF) DC hybrid magnetic bearing (HMB) for supporting the high-speed motor is proposed. The rotor in the novel HMB is easy to achieve 5-DOF stable levitation, of which the decoupling and levitation performance are enhanced. The equivalent magnetic circuit method (EMCM) and finite element analysis (FEA) are employed to verify its reliability and rationality. The mathematical formulas of levitation forces are obtained, and the basic performances of key electromagnetic parameters are simulated and confirmed. It can be concluded that the proposed 5-DOF DC HMB has reasonable magnetic circuits, and can produce the 5-DOF levitation forces in one unit. Moreover, the mathematical models are correct.
