The new type actuator by applying the EHD phenomenon Development of the EGD Motor

The purpose of this study was to develop the new type actuator which has flexibility by using an EHD phenomenon for the application to the small machine or welfare system. The EHD phenomenon is a phenomenon that generates the flow in the insulating fluid by applying a high voltage electric field. Especially, rotation type actuator using an EGD phenomenon was developed by this study. And, EGD (Electro Gas Dynamics) phenomenon is a kind of the EHD phenomenon which occurs in the gas. Then, this actuator was called EGD motor. The EGD motor has one pair of electrode, one of these is a cylindrical electrode for a stator and another is L shaped electrode for a rotor. We changed the shape of electrode and measured the torque and rotation speed, to evaluate the rotational performance of the EGD motor
