Dynamic Characteristics 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 single-phase or two-phase voltage. The proposed actuator has two difference vibration characteristics, and it effectively generates vibrations with differential frequencies. In this paper, the dynamic characteristics are clarified by finite element analysis.
