World's first sandwich-structured manufacturing uniformly enhancing high-power motors' thick neodymium magnets' performance

"difficult to diffuse performance-boosting elements into thick magnets' core, overcome inserting light rare earth alloy between layered magnet slices initiating diffusion from inside out... significantly increases coercivity throughout entire structure without relying on expensive/ scarce heavy rare earth elements like dysprosium... simultaneously creates high-resistivity internal structure suppressing efficiency degrading heat generating eddy currents... smaller, powerful, efficient motors: electric vehicles, ships, wind turbines"
