Abstract
An axial hybrid magnetic bearing (HMB) is disclosed herein. The HMB has a first electric magnet, a second electric magnet, and a rotor being between the two electric magnets. The rotor has a permanent magnet (PM) structure facing the two electric magnets by its two sides. By doing so, the power consumption can be lower by a bias magnetic flux provided by the PM structure; the equilibrium point of the rotor can be adjusted by the magnetic force of the two electric magnets, which will not change the magnetic characteristic of the PM structure.
