Abstract

PURPOSE: To reduce the size and the thickness of an electrostatic motor, by arranging a comb type common electrode and a plurality of electrodes on the end face of a cylindrical rotor thereby generating charges between electrodes of rotor and stator.
CONSTITUTION: An electrostatic motor 13 comprises three electrodes 2a∼2c of stator 3 and a common electrode 5 of rotor 8, while a contact spring 11 for electrically conducting a drive circuit with the common electrode 5 is provided. The stator 3 comprises an insulator 1 and a plurality of electrical conductor electrodes 2, while the rotor 8 has the common electrode 5 arranged on a circular insulator 6 and a central shaft 7. A frame 10 is secured with the stator 3 and has a bearing for the shaft 7 of the rotor 8. The common electrode 5 at the opposite ends of the rotor has an integrated radial electrode portion at the end face and a ring electrode portion near the shaft. Consequently, the rotor 8 can be rotated by simply applying voltage onto the plurality of electrodes 2 of the stator 3 and the common electrode 5 of the rotor 8 and generating charges.
