KIMS Develops Breakthrough Magnet Technology for High-Performance Motors
The Korea Institute of Materials Science has introduced a new magnet manufacturing technology that enhances performance and reduces heat generation, crucial for high-power applications like electric vehicles. This innovation potentially transforms the market for high-efficiency motors and reduces reliance on heavy rare earth elements.
Theia Market Signal Identification - AI AssistedThe Korea Institute of Materials Science (KIMS) has developed a novel magnet manufacturing technology that uniformly enhances magnetic performance in thick magnets while minimizing heat generation. This sandwich-structured grain boundary diffusion process employs a light rare earth alloy, praseodymium, which initiates diffusion from within the magnet layers.
The technology enables stable coercivity and improves motor efficiency, addressing issues of eddy current formation and performance degradation. It is anticipated to significantly impact electric vehicle traction motors and wind power systems, while reducing dependency on imports and expensive heavy rare earth materials. The findings, published on March 18, 2026, in Scripta Materialia, demonstrate the potential for broader applications in high-performance magnets.
