Disk-Plate-type Micromotors using ECF

Configuration of DP RE ECF motor

DP-type Micromotors using Electro-conjugate Fluids (ECF) are proposed and developed. ECF-jet is much suitable for thin plate type motor with very thin clearances as a channel through the jets. It is ascertained that a higher power micro motor can be obtained by making it much thinner in the inner height and integrated more layers in it. Recently, a high-integrated eight-layered ID 9mm DP-RE-ECF micro motor and ID5mm Micromotor are proposed and fabricated as shown below.
