Tubular linear induction motor for hydraulic capsule pipeline. I. Finite element analysis

An axisymmetric model of the magnetic field of the tubular linear induction motor (TLIM) for application to hydraulic capsule pipelines is developed using finite element method (FEM) analysis. The FEM model is used to analyze a specific TLIM design at standstill for a given supply current. The finite element formulation of the field equations is discussed and the magnetic field contours at different instants of time are presented. FEM computation of the thrust compares very well with experimental data.<
