Electromagnetic Modeling of a Linear Synchronous Machine by Lumped Approach
College of Logistics Engineering, Shanghai Maritime University, Shanghai, China
This paper presents a quantitative analysis method for electromagnetic device called lumped approach. This approach is based on combination of magnetic circuits and finite element method, which provides a good compromise between time calculation and accuracy. The authors propose an electromagnetic model for a linear synchronous machine through this lumped approach. In this research, the linear machine is separated into many small parts. Then, compute all the magnetic reluctances of them with analytical method and acquire the reluctance network. After that the authors couple the electrical part and magnetic part through electromagnetic coupling method. At last, the authors simulate the electromagnetic model of the linear machine and compare the result with that of finite element method.
Key words: electromagnetic device / lumped approach / linear synchronous machine / electromagnetic coupling
