NdFeB Permanent Magnets Are a Critical Factor?]( "Why Source Robot Joint Modules from China? NdFeB Permanent Magnets Are a Critical Factor?")
Why Source Robot Joint Modules from China? NdFeB Permanent Magnets Are a Critical Factor?Humanoid robotics is often described as a software race, but the real constraint on scaling production to millions of units lies in the physical layer. Robot joints require high-torque, high-efficiency actuators, and actuators depend on high-energy-density NdFeB permanent magnets. The true bottleneck is not simply “rare earths” in general, but the much narrower NdPr-to-magnet supply chain corridor. China dominates the midstream processing and magnet manufacturing sectors, giving it significant influence over the pace, cost curve, and industrial geography of embodied AI.
