Abstract

The paper presents a novel approach of analyzing demagnetization phenomenon in permanent magnet (PM) machines. Experimental measurements of electromotive force (EMF) results for example, have been used to calculate the magnet´s remanent induction (B_r) in its different regions. Resolution by Maxwell´s equations and gradient based algorithm is applied to solve this inverse problem. The research is a continuation of the work presented [J. Farooq et al., 2006], where demagnetization modeling analysis is taken as a direct problem
