Micro-Gyro-motors without rotating shafts using Electro-conjugate Fluids (ECF) are proposed and developed. The ECF is a kind of dielectric fluids and produces jet flow from rod-type or needle-type electrodes in an applied static electric field. The ECF allows　direct converting electrical energy to mechanical energy. The proposed micromotors have simple structure, very light-weight and are driven by a direct-current electric power supply.
