This paper reports the development of micro motors using Electro-Conjugate Fluids (ECFs). ECF is a kind of dielectrc fluids, which produces jet-flow by applying high DC voltage between electrodes inserted in the fluid. By applying this phenomena of ECFs to motor principle, simple structure and lightweight micro motors can be realized. We call these motors ECF micro motors. In this study, effect to the output characteristics of DP-RE-type ECF micro motors for increasing the electrodes thickness is investigated by using 2-layered DP-RE-type ECF micro motors with inner diameter φ9mm and inner height 1.9mm, and also 8-layered DP-RE-type ECF micro motor with inner diameter φ9mm and inner height 1.0mm is designed and fabricated in order to realize more poweful multi-layered DP-RE-type ECF micro motors. In conclusion, it is confirmed it is effective to increase electrodes thickness for realization of more powerful DP-RE-type ECF micro motors, and obtained max. output torque is 55μNm at 6kV for fabricated 8-layered DP-RE-type ECF micro motor.
