Greaves Cotton partners with Chara Technologies on rare-earth-free motor production

Greaves Cotton Limited has announced a partnership with a Bangalore-based startup Chara Technologies to manufacture synchronous reluctance motors and controllers that do not use rare-earth magnets. These components will be manufactured by Greaves at its facility in Shendra, Aurangabad, and will be used in both automotive and non-automotive applications, including L5 three-wheelers, golf carts, and four-wheelers.

This collaboration combines Chara’s technology in motor systems with Greaves’ manufacturing and research capabilities. Chara’s synchronous reluctance motors and controllers are designed to reduce electromagnetic losses by eliminating the use of rare-earth magnets, which can help address supply chain risks associated with sourcing these materials. According to the companies, the removal of rare-earth elements from these components can result in energy savings (up to 50%) and reduced carbon emissions (by 30%), due to the different raw materials used.

The global automotive sector continues to experience challenges such as supply chain disruptions, labor shortages, and regulatory requirements. The development of rare-earth-free motor systems is one of the responses to these issues, aiming to make supply chains more adaptable. The partnership is expected to support Greaves in developing electric motor solutions tailored for original equipment manufacturers (OEMs) in India’s electric vehicle sector.

Speaking about the collaboration, Dr. Arup Basu, Managing Director, Greaves Cotton Ltd., said: “We are committed to enabling and scaling sustainable mobility through innovation and collaboration. Given our design agnostic approach, we partner with start-ups and technology experts to offer bespoke prime mover solutions with a focus on sustainable mobility. Our partnership with Chara Technologies aligns well with our vision and long-term strategy to leverage emerging technologies to build supply chain resilience and usher in manufacturing excellence in the electric mobility ecosystem, thereby positioning India as a key global player in clean mobility transformation.”

Mr. Bhaktha Keshavachar, Founder & CEO, Chara Technologies, said: We are truly honored and excited to partner with Greaves, a pioneer in India’s electric mobility landscape. This collaboration is a significant milestone for us at Chara as we continue building and delivering next-generation, rare-earth-free motor technologies. By combining Greaves’ deep industry expertise and expansive reach with Chara’s pathbreaking tech and product know-how, we see a powerful opportunity to accelerate the transition to clean mobility and contribute to India’s journey towards technological and energy independence. Our motor and controller systems offer a timely, efficient, and scalable solution – not just for India, but for global industries seeking secure and sustainable electrification solutions.”
