Comparison of optimal shape design by continuum approach in constant flux and constant current problems

Abstract

Commercial electromagnetic analysis software can be used for optimal shape design with continuum design sensitivity analysis method since the continuum approach is a nonintrusive method. To simulate the externally forced magnetic field, two types of conditions - constant flux and constant current - Are usually used. To demonstrate that the constant flux and constant current conditions produce very different designs, a direct comparison of optimal shape design using the continuum approach is presented in this paper.
