TRANSIENT ELECTROMAGNETIC ANALYSIS COUPLED TO ELECTRIC-CIRCUITS AND MOTION

This paper presents implementation details of coupling circuit equatio ns and motion with two dimensional finite element models for transient magnetic analysis. Finite elements with incomplete shape functions ar e used in a novel way to handle the interface between the moving and s tationary parts of the mesh. The final system of equations can then be solved using adaptive time stepping. Two examples are presented, a ge nerator, which is coupled to motion and a motor, which is coupled to e xternal circuits.
