Novel Modification Method using Laplace Equation for 3-D Motion Analysi with Finite Element Method

摘要

In the dynamic analysis for electromagnets and motors by three-dimensional (3-D) finite element method, it is necessary to modify the 3-D meshes according to the position of the armature. In this paper, we propose a novel mesh modification method in which the displacements of nodes are calculated by solving the Laplace equation. This method can be applied to the armature movement of electromagnet, the skewed rotor and the off-centered rotor of motors, and so on.
