자기적 비선형을 고려한 Moving Magnet Linear Actuator의 설계 및 동특성 해석

Design and Dynamic Characteristics analysis of Moving Magnet Linear Actuator Considering the Magnetic Nonlinear phenomena

This paper is proposed a new linear actuator with the permanent magnet on the mover. This linear actuator is designed to produce the vibration of a osillator. In order to evaluate its dynamic performance, the equivalent coupling parameter between mechanical and electromagnetic equations of the linear actustor, which is considered the magnetic nonlinear phenomena, is analyzed by the finite element method and estimated the thrust, displacement and acceleration with the simualation values and the experimenta ones.
