Recently, Y. Otsubo et al reported that a kind of dielectric fluid such as dibutyl decanedioate produced jetflow by applying high voltage electrostatic field. The fluids are called Electro-conjugate Fluid (ECF). We proposed novel micromotors by making use of ECF. In this paper, firstly, a micromotor whose disk plate-type rotors are layered in multiple is proposed. High torque and high power density are produced with the multi-layered motor. Secondly, characteristics of the fabricated multi-layered motor are experimentally examined by comparison between a single-layered-rotor and a double-layered rotor. It is confirmed that the double-layered rotor produces twice as high torque and power as the single-layered rotor. Finally the I. D.φ9mm double-layered micromotor is fabricated. Characteristics of the fabricated motor are examined.
