%X this paper presents a new type of magnetic bearing with active control only in axial direction. the bearing uses two pairs of permanent magnets working in attraction mode to restrict the radial motion and a control system composed of two electromagnets, a gap sensor and a controller to keep the axis in a fixed axial position. the principle, the dynamic model for axial motion and the control system for this bearing are presented. finally, by experiments conducted in a prototype, the effectiveness of the presented concept is shown.
