Authors Miguel A Marioni 1 , Marcos Penedo 1 , Mirko Baćani 1 , Johannes Schwenk 1 2 , Hans J Hug 1 3 Affiliations WebThe self-shielding effect of Halbach arrays can be used to significantly decrease the flux density in the magnetic gear’s back irons. In turn, this can be used to build a smaller, lighter gear while maintaining performance ratings and even decreasing losses (especially since the arrays also decrease harmonic amplitudes).
