컨버팅 장비용 중공형 MR 브레이크 설계에 관한 연구

In this study, a hollow MR(Magneto-rheological) brake instead of conventional powder brake is presented for high-tension control of converting machinery such as coater, slitter and so on. First, to obtain the higher performance than conventional powder brake, a hollow MR brake is newly mechanism designed and analyzed by using electromagnetic field analysis. Second, a prototype of the hollow MR brake is fabricated considering the converting machinery installation and an experimental apparatus is constructed. Finally, basic characteristics between current and torque are experimentally investigated.
