The method to design the interference fit for the rotor components of the active magnetic bearing (AMB) was proposed. The rotor components include the thrust collar, the radial bearing rotor components and the sensor rotor components. Four main influencing factors and the machining accuracy are considered during the designing, such as the centrifugal force, the loadings, the thermal expansion coefficient, the electromagnetic force, and the coupling surface roughness. Some calculation examples were presented. These examples are base on the AMB of a helium blower, which is going to be applied in the High Temperature Reactor-Pebblebed Modules (HTR-PM) in Rongcheng City, Shandong province. Both the analytical calculation and the finite element analysis were carried out, and then were compared. The method of design based on the simple analytic formula was proved to be available.
