Design and dynamic characteristics analysis of moving magnet linear actuator for human

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 an oscillator for human body. In order to evaluate its dynamic performance, the equivalent coupling parameter between mechanical and electromagnetic equations of the linear actuator, which is considered the magnetic nonlinear phenomena, is analyzed by the finite element method and estimated the thrust, displacement and acceleration with the simulation values and the experimental ones.
