Rotational Electrostatic Motor with Air Bearing

Electrostatic motors have many advantages such as convenience in fabrication and compactness. In this paper, a rotational electrostatic motor with air bearing (350 _m gaps) is designed and fabricated. The components of this motor include a disc as rotor and one or two series of electrodes with rotational arrangement which are fabricated by PCB technology, as stator. In this study, rotor is Plexiglas disc with 38mm in diameter and 1mm thickness. To reduce friction between rotor and stator an air bearing is used. Also, kinetics, design and fabrication process of a prototype is described and then some parameters influencing on motor operation is investigated experimentally. Results show successful motor operation and In addition high rotational velocity is archived in this motor.
