New Construction of an Electro-Conjugate Fluid-Jet-Driven Micromotor with an Inner Diameter of 2 mm

Abstract

Electro-conjugate fluid (hereafter abbreviated as ECF) is a kind of dielectric fluid that produces a powerful jet flow (ECF jet) between rod-type electrodes in an applied non-uniform static electric field. By using the ECF jet, a new type of micromotor with a simple structure and light weight can be realized. Until now, some types of ECF micromotors have been developed with a 3 mm inner diameter. In this study, a micromotor is fabricated with a 2 mm inner diameter in order to improve the output power density, using the ECF jet. The micromotor was first designed and fabricated; then, the performance of the motor was measured. The experimental results confirm that the micromotor developed here has a higher power density than the micromotors previously developed with 3 mm inner diameter.
