The energy-saving actuation system is a valuable element in various industry fields using micro mechatronics technology. In the recent five years, we have produced some kinds of proto-model of novel contact-free disk suspension and linear motion devices by using diamagnetic graphite (Pyrolytic Graphite: PG) plate. Especially, a contact-free linear drive by using PG plates and small piece magnets is very useful as an extremely energy saving actuation technique. Very recently, we got a unique result as a successive acceleration motion of PG plate on Halbach PM array. We are getting ready to confirm it by using ring Halbach PM array.
