57 Abstract AB [EN] PCT No. PCT/DE90/00067 Sec. 371 Date Oct. 21, 1991 Sec. 102(e) Date Oct. 21, 1991 PCT Filed Feb. 2, 1990 PCT Pub. No. WO90/09057 PCT Pub. Date Aug. 9, 1990A motor whose torque is not generated by magnetic fields but rather by dielectric forces to be used in microelectronics and micromechanics. The rotors are composed of several dielectrics, which are arranged in a sector-shaped or shell-shaped manner or partially or completely envelop each other. These motors can be miniaturized down to a size of a few millimeters. They are distinguished by having slow to medium rotation speeds, short starting phases (ms range and less), extremely low current consumption, simple construction, high running constancy and being practically maintenance free. The characteristic curve of rotation (rotation as the function of the field frequency) may be selected in many ranges by changing the dielectrics of the rotor.
