A type of electromagnetic biased axial magnetic bearing is studied. Compared with traditional axial magnetic bearings, it has a smaller external diameter of the thrust plate, which is helpful to improve the critical speed of the rotor in theory. The structural parameters are obtained and finite element model(FEM) is established. The magnetic flux leakage coefficients and the magnetic resistances are calculated. The rationality of parameter design is verified. The results show that the parameter design and the electromagnetic field simulation are in accordance with rationality of the design. Therefore, the magnetic biased axial magnetic bearing is not only simple in structure, but also reasonable in design, which is of great significance to the design of magnetic bearing.
