摘要：This paper proposes a novel eight-pole heteropolar radial-axial hybrid magnetic bearing (HMB) to reduce the power consumption and to improve the space utilization of the entire system. The mathematical model of HMB is obtained by applying the equivalent magnetic circuit method. And its bearing capacity in both the radial and axial directions is analyzed. Also, to maximize the bearing capacity, the structural parameters of HMB are designed. The magnetic field distribution and the magnetic induction intensity across the air gap are studied by the 3D Finite Element (FE) simulation. And the force/current and force/displacement characteristics are then attained. Experiments on the investigated HMB are carried out to validate the modelling results. It has been shown that the maximum bearing capacity of the HMB is 190 N and 170 N in the radial and axial directions respectively, which are the 82.6% and 81% of theoretical value. © 2019 IOS Press and the authors.
