Nonlinear transient finite element modeling of a capacitor-discharge magnetizing fixture

Abstract

A modeling approach for the simulation of a capacitance-discharge magnetizer used for the magnetization of permanent-magnet materials is presented. The modeling approach involves the solution of the coupled voltage excited electric circuit and nonlinear transient magnetic field problem. The approach uses zero-, one-, and two-dimensional finite elements to solve directly for the transient electromagnetic field distribution in a multiturn capacitor-discharge-driven magnetizing fixture.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
