Experimental Evaluation of Linear Oscillatory Actuator with Two Movers

Abstract

　Electromagnetic type linear oscillatory actuators are used in many devices because of high controllability and small size. We developed a linear oscillatory actuator with two movers that can independently drive by impressing same-phase or reverse-phase currents. The proposed actuator has two difference vibration characteristics, and it effectively generates vibrations with differential frequencies. In this paper, we clarify the characteristics thorough measurements on a prototype.
