| Abstract: | The research and development process of a novel moving-magnet linear motor for linear compressor were presented.Based on the magnet circuit analysis,the dynamic equation of moving part was solved coupling with the voltage balance equation.As a result,the displacement of moving part is expressed as the function of input voltage and some other geometrical parameters.The finite element method was used to optimize the electromagnetic field and reveal the mechanism of motion of moving part.Finally,the comparison between the experimental data of prototype linear motor and the numerical solution not only verifies the effectiveness of finite element method but also indicates the relationship between the force,displacement of moving part and current,which lays the foundation for designation of linear compressor and control system. |
