Original optimization procedures of halbach permanent magnet segmented array

Abstract

This paper presents a direct design and optimization procedures of an arbitrary PM Halbach Segmented Array. The direct design is based on the ideal PM Halbach definition. The arc width, magnitude and orientation of polarization of each segment are taken as optimization variables after calculation of PM thickness. A new optimization procedure based on integration of Least Square Method inside the well-known Sequential Quadratic Programming method is proposed to improve the optimization results and to reduce time computation.
