Abstract
A Halbach cylinder, fabricated from pre-magnetized sintered NdFeB magnet se gments, is proposed for the powder aligning system during the compression o r injection moulding of anisotropic bonded Halbach oriented NdFeB ring magn ets, The influence of leading design parameters of the powder aligning syst em, viz. the number of magnet segments per pole, their axial length and rad ial thickness, and their clearance from the mould, is investigated by finit e element analysis, and validated experimentally.
