The design of a miniaturized spindle system applied active magnetic bearings(MB) is discussed. The proposed system is consisted of radial and axial magnetic bearings. The radial magnetic bearing is hybrid type, permanent magnet for bias magnetic flux and electromagnet for control current. And the axial magnetic bearing is only used electromagnet. Therefor this system is a 5 degrees of freedom active control system. In this paper, we suggest the design specification, such as stiffness, length and width of each part, including permanent magnet. We will apply this spindle system to micro machine tool system for micro factory.
