PURPOSE: To provide a new actuator which uses an operating medium to convert electric energy into kinetic energy based on a new principle of operation. CONSTITUTION: An ester represented by the general formula R1 OOC(CH2 )x COOR2 wherein (x) is an integer from 4 to 12 and R1 and R2 are each an alkyl group of 1 to 13 carbons, is put in a cylindrical case 1 as an operating medium 11, a plurality of electrodes 3a, 3b...3h are provided on the inner peripheral wall of the case 1, impeller-like rotors 6a, 6b are placed inside the case 1, voltages are applied to the electrodes 3a, 3b...3h, and the rotors 6a, 6b are rotated by the operating medium. |
