Micromotors Using Electro-Cojugate Fluids(ECF) |
|
|
|
|
 |
Dr.Ootsubo, Professor of Chiba University, one of our co-researchers, has found a kind of dielectric liquids. We call the liquid as Electro-Conjugate Fluids (ECF)
ECFs produce strong jet flow when applied high electric field between rod-type poles.
We apply the ECF to micro-motors which have simple structure and very light-weight.The micro Motors have two-types, Cylinder-type and Disk-Plate-type.
The photo shows C-stator-type ECF motor with ID4mm (0.6grams), 3500rpm@6kV, max efficency 17%. Also, the rotary-type has a potencial to have greater power.
