Magnetic field exploration on single sided linear induction motor used finite element method
Abstract
L inear induction motor plays a great important part in linear motion drive and can absolutely replace the rotor induction motor. Therefore, it is very necessary to do research on linear induction motor. The in-depth exploration of electromagnetic behavior of linear induction motor has been a fundamental step for investigations of linear induction motor. In this study, the combination of the equivalent circuit model with electromagnetic field model of a single-sided linear induction motor is carried out, by giving calculation results from equivalent circuit model inputted to electromagnetic field model, based on finite element method (FEM) model in using the software 2D-FEM to solve electromagnetic field problem. At the same time, we survey the magnetic field of the air gap, the asymmetry of the magnetic field and eddy current in the secondary section.... The presented characteristics are good basis for steady-state analysis of the LIM in researches later on.
