Uncommon earth elements are really essential in electric vehicles because they improve the performance of the engines. They have special magnetic properties that make motors more competent, powerful and capable of producing more torque. electric vehicles operate two essential scarce earth elements: neodymium (Nd) and Dysprosium (Di). Neodymium is particularly essential because it is used to make magnets called neodymium-iron-boron magnets, which are used in engines.
We recently spoke with Bhakta Keshavachar, CEO and co-founder of Chara, a technology startup focused on engine systems free from scarce earth elementsto understand how Chara co-creates this space.

Speaking about Chara’s patented “bright motor systems” design and how they differ from conventional motors, Keshavachar said: “Our initial estimates suggest a reduction in energy consumption of 1 Gigaton CO2 emissions and 1 GigaLiter of water consumption per year compared to classic engines. But the benefits go beyond that. Uncommon earth-free motors achieve efficiency and performance comparable to enduring magnet motors, which has the potential to translate into significant reductions in energy consumption and overall costs of electric vehicles.”
Developing engines tailored to specific applications requires a deep understanding of the unique needs of each vehicle segment. For example, two-wheelers require compact and lightweight designs for maximum range. Three-wheeled vehicles, on the other hand, require high torque to handle weighty loads.
“Unlike classic engines, we completely bypass the variability associated with scarce earth elements. Our engines rely solely on naturally occurring materials such as steel, aluminum and copper, which feature geographically diverse and accessible supply chains. To further strengthen our position, we have partnered with many suppliers of these materials, ensuring reliable flow. explained how supply chain disruptions will not impact the production of these engines if inventory flow is maintained.
Regarding Chara’s international standing, Keshavachar discusses the importance of their patented design in breaking the global monopoly on scarce earth materials in electric motors. “We have already started to receive inquiries from companies in Europe and North America, which shows the growing international interest in solutions that take into account the environmental impact of scarce earth mining.”
In response to inquiries about environmental impacts, Keshavachar highlighted the significant environmental damage associated with scarce earth mining. “For every tonne of scarce earth elements produced, a staggering 2,000 tonnes of toxic waste is produced. This applies to dust, waste gases, sewage and radioactive residues. The mining process pollutes the air, water and soil due to the operate of harsh chemicals and the presence of radioactive materials in the ore itself.
“These figures paint a disturbing picture of the environmental damage associated with REE mining. Of particular concern are the potential for water contamination from leaking leach ponds and the long-term health risks posed by radioactive materials.” he added.
“To break China monopoly on electric motorsIndia needs to invest in high-tech research and development to seek materials that can be sourced within India itself to produce functional and competent engines, support domestic manufacturing and invest in creating a skilled workforce along with support policies. Considering the current demand for electric vehicles in the country, which is enabling the growth of companies like ours, it is protected to say that we are on the right track,” Keshavachar noted.
