Some kinds of dielectric fluids as dibutyl decannedioate generate jet flow between electrodes. One of the authors calls the fluids ECf (Electro-conjugate Fluids), which are considered as smart fluids. The authors propose a micro motor by making use of ECF. In our previous paper, a rotor electrode(RE)-type micro ECF motor have been reported In the paper, fabrication of micro ECF motors having I.D.ø3mm, I.D.ø4mm, I.D.ø8mm is described. On the RE-type micro ECF motor, some pairs of electrodes are located on the surface of a cylindrical rotor. The rotor can rotates with the reaction force caused by ECF jets. By making use of the ECF jet’s reaction force, micro motors are easily realized. In this paper, fabrication of a micro ECF motor having I.D.ø2mm is described. Also, Basic characteristics such as rotational velocity are experimentally examined.
