Hybrid magnetic bearing is recognized as an efficient one even with wide airgap and is suitable for such application. Previously sub-pole type IPM hybrid magnetic bearing has been proposed. However the sub-pole produces bias flux and cannot produce control force. To overcome this problem, two new types of hybrid magnetic bearings are proposed which have permanent magnet within the stator core. This paper introduces structure and principle of the proposed magnetic bearings. The geometric parameters of these new type mechanisms are optimized by FEM analysis. The experimental setups are made based on these analytical results. The fundamental characteristics are measured and compared with the estimate bearing performances. The results show stable levitation and good rotated levitation.
