Numerical Analysis of Starting Characteristic of Tubular Linear Induction Motor Based on Finite Element Method

The starting process of Tubular Linear Induction Motor is simulated dynamically on the basis of two-dimensional (2-D) finite element analysis method and the parameters are calculated and analyzed numerically, such as starting thrust force, magnetic field density, flux linkage, velocity and placement of mover as well as magnetic flux density in the air gap, etc.. The computing results indicate that thrust force and magnetic flux density in starting process is greater than one in stable progress, and varies of thrust force is along with the mover´s materials. The calculating results are available for further studying of tubular linear induction motor and its controlling system.
