Magnetizer Design and Analysis for the Permanent Magnet Machines

Abstract

The paper presents the numerical design and the analyses of the magnetizer for the permanent magnet machines. The design based on the numerical optimization is integrated into the nonlinear finite element method. The numerical optimization is the Nelder-Mead simplex search algorithm. The nonlinear system of equations according to the nonlinear characteristics of ferromagnetic material and of the permanent magnets can be handled by the fixed point technique with polarization method.
