Advanced magnet manufacturing begins in the United States

Engineering research across multiple U.S. laboratories is advancing the development of electric motors that don't rely on rare earth elements (REEs), exploring alternatives like ferrite magnets, alnico alloys, and innovative electromagnetic designs. While current REE-free motors show performance limitations compared to traditional rare earth-based motors, promising breakthroughs in design and materials could eventually eliminate this gap. Recent developments, including ZF Group's electromagnet-based motor and GE Aerospace's dual-phase magnetic material, demonstrate significant progress toward commercially viable REE-free alternatives.
