| Research Abstract |
Since 2007, we have worked on development of planar contact-free micro motion model using diamagnetic graphite (Pyrolytic Graphite : PG) plate above two dimensional (2D) Halbach permanent magnet array. And, we realized precise micro motion control of octagonal PG plate sample above 2D Halbach PM array by using an approaching PM piece. On the project since 2008, in order to make more precise displacement characteristics, we focused on the improvement for magnetic stiffness of the octagonal PG plate sample by two kinds of improved model above 2D Halbach PM array. Then, on the basis of this result, we conducted to explain the displacement response of the octagonal PG plate sample by using a piezo linear actuator for the approach system of a small PM piece in the present model. We could take the preliminary measurement result of the displacement response depending on the present models.
