Abstract
An electrostatic motor includes a cylindrical rotor and a stator. Electrodes are disposed on an inside cylindrical surface of the stator. Electrets and/or electrically conductive electrodes are disposed on the cylindrical rotor and a dielectric fluid fills space between the rotor and the stator to prevent discharge of the electrets. A mask is used to charge portions of an electret cylinder or other curved surface.
