Characterization of Magnetic Anisotropy for Binder Jet Printed Fe93.25Si6.75

Isotropic magnetic properties are important for electrical machine topologies that require 3D flux paths. Soft magnetic composites, which have been used to manufacture magnetic cores for these designs, have limitations. Additive manufacturing technologies provide flexibility to fabricate ferromagnetic structures that can overcome challenges inherent in manufacturing soft magnetic composites. In this paper, the magnetic anisotropy of binder jet printed iron silicon samples is quantified and compared with commercial soft magnetic composite material.
