The design of a moving-magnet linear oscillating motor for linear compressors

摘要

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.
