Abstract
The fundamental theory and simplified model of moving-magnet 1inear oscillating motor are presented in this paper. Based on the analysis of the equivalent magnetic and electric circuit model, a 2D finite element (FE) model of a linear oscillating motor with two separated stators is established. Through the FE simulation, the effect of the input voltage on the electric-magnetic force and displacement is investigated. The efficiency of the motor is estimated according to the analysis.
