Saarland researchers use 3D-printed metallic glass motor parts to cut iron losses

Researchers at Saarland University say they have developed iron-rich amorphous alloys for electric motor components that can reduce remagnetization losses by eliminating the crystalline microstructure that causes internal friction and heat buildup in conventional soft-magnetic materials. The project focuses on replacing coarse-grained crystalline iron alloys used in stators and rotors with metallic glasses containing 70% to 80% iron. According t…
