Tata Elxsi’s rare earth-free motor’s simple, robust design minimises wear. As it reshapes the auto landscape, India’s reliance on specific sources dwindles, steering away from China’s rare-earth dominance
In a conversation with the Electronics For You team, Tata Elxsi revealed it is developing an electric vehicle motor that, instead of rare-earth metals, relies on ferrite.
The company asserts that this motor will assist India and its vehicle manufacturers in reducing dependence on China for the importation of rare-earth metals. Rare earth metals, such as Neodymium (Nd) and Dysprosium (Dy), find use in permanent magnet motors globally. China dominates the production of Nd and Dy, contributing to 67% of the total, followed by Myanmar (12%), Australia (10%), and the United States (9%). Conversely, ferrite is produced by combining iron oxide with metallic elements like barium, manganese, nickel, strontium, and zinc. According to the Volza website, India ranks among the top three importers of Dy and Nd.
