EHD現象を応用した回転型アクチュエータの開発: EHDモータの開発

摘要

The purpose of this study was development of the rotation type actuator that applied the EHD phenomenon. The EHD is a phenomenon that generates the flow in the insulating fluid by applying a high voltage electric field. In this study, firstly, the electrode arrangement which makes the strong EHD phenomenon was investigated and the EHD motor applying that electrode arrangement was developed. In the next step, the EHD motor using the developed electrode arrangement was manufactured as an experiment. Then, the electrode arrangement of the EHD motor was changed, and the performance change of the EHD motor was examined.%EHDとはElectrohydrodynamics（電気流体力学）の略称で，rn絶縁性流体に直流電圧を印加すると電極間に流れが発生する現rn象をEHD現象と呼ぶ．この現象は1950年代に数元らによりrn発見されていたが，従来EHD現象に関する研究にはシリコーrnンオイルや機械油等の流体が用いられ，これらの流体は発生すrnる圧力が数100Paと弱いものであった．
