Abstract
This paper reports the development of micro motors using Electro-Conjugate Fluids (ECFs). ECF is a kind of dielectric fluids, which produces jet-flow by applying high DC voltage between electrodes inserted in the fluid. By applying the phenomena of ECFs to motor driving principle, simple structure and lightweight micro motors can be realized. We call these motors ECF micro motors. In this study, we designed and fabricated φ5mmI.D. 4-layered and 8-layered DP-RE-type ECF micro motors are miniaturized in order to improve the output power density. Also we investigated the characteristics by experiment in the case of using high performance ECF in order to confirm possibility of improvement of output characteristics. In conclusion, it is confirmed that it is effective to miniaturize ECF micro motor and use high performance ECF for improvement of output characteristics.
