In this work, we introduce a newly developed passive and frictionless diamagnetic contactless suspension rotor with electrostatic glass motor. A 20 mm diameter disc-shaped rotor comprised of pyrolytic graphite with glass is fabricated. The rotor is diamagnetically and passively levitated by an array of Nd-Fe-B magnets at room temperature without any energy supply. To realise the rotating function, a 700 V high voltage electrostatic glass motor is designed and arranged in the levitation air gap between the rotor and the magnets. To install the stator in this narrow air gap, we fabricated the stator using a flexible printed circuit with 100 mu m thickness. The newly developed system is more compact, stable and of high performance. The maximum speed has been improved doubly to 300 rpm in atmosphere. We intend to draw attention to this uncommon levitation and to show that it could be used for micro-mechatronic system.
