Abstract

Linear oscillatory actuator can produce high-speed rectilinear vibration efficiently, without motion converting mechanisms. However, we need to reduce the reaction force and moment caused by main vibration for its application. <br>So far, the method for vibration reduction that two moving elements of magnetic circuit are counter driven is reported, but it needs complicated construction for cylindrical models. <br>In order to solve this problem, we propose linear oscillatory actuator with dynamic vibration control as a new construction and describe its principle of operation. Furthermore, we evaluate the performances of the actuator by computer simulation and confirm them by a prototype.
