三入力で駆動する二つの可動子を有するリニア振動アクチュエータの提案

抄録

　Electromagnetic type linear oscillatory actuators are used in many devices because of high controllability and small size. In previous studies, a linear oscillatory actuator with two movers and two coils that effectively generates vibrations in a wide frequency range by impressing same-phase or reverse-phase current, is developed. However, two H bridge circuits are needed for driving the actuator. In this paper, a new actuator with two movers that can drive using a three-phase inverter, are proposed. First, the characteristics of the proposed actuator are clarified by finite element analysis. Finally, there are compare with those of the conventional actuator.
