Investigation of Optimal Design of LIM-type Electromagnetic Stirrer using Rosenbrock's method

Abstract

　The determination problem of optimum position and shape of exciting coil and teeth of LIM-type electromagnetic stirrer is discussed. 3-D magnetic field FEM analysis and Rosenbrock's method are used. Design guidelines for minimizing power capacity and maximizing flux density are examined using the objective function, that is the inverse of evaluation factor including the flux density at a specified position and load inductance. It is shown that the coil position affects mostly the performance of stirrer.
