    Abstract: The present invention relates to a dielectric motor which is driven by means of electric fields. The motor is distinguished by two or more dielectric rotors being disposed in a central region which is surrounded by several electrodes.The rotors may be made of different dielectric materials and be electrically axially asymmetric in design. They are driven by continuously or discontinuously rotating electric fields. Depending on the geometric and electric design, very variable rotation conditions can be achieved, which can be simply controlled via the frequency of the rotating fields. The motor is suited for switch and drive purposes and can be utilized to construct microdosing devices, pumps and valves.
