As reported by Newswise in the article “Scientists Develop Rare Earth Free Magnet for Use in Industrial Motors,” a new breakthrough from the U.S. Department of Energy’s Ames National Laboratory could mark a pivotal shift in industrial motor efficiency and sustainability.
Most modern factories rely on industrial induction motors, but permanent magnet motors are typically more efficient. The challenge? These motors often depend on rare-earth materials—expensive, limited in supply, and over-engineered for many industrial needs. This reliance poses not just a cost burden but also risks related to global supply chain disruptions.
