India-based Sona Comstar significantly expanded its technology development efforts during FY2026, supported by a research and development investment of INR 1,015.89 million. The Sona Comstar R&D Investment program focused on improving electric mobility technologies, advancing power electronics capabilities, and strengthening indigenous engineering expertise. The company disclosed these developments in its annual report for the financial year ending March 2026, highlighting progress across motor technologies, inverter systems, and manufacturing processes.
Advancements in Electric Motor and Magnet Technologies
Among the major developments completed during the year was the creation of magnets using Cerium as a substitute for heavy rare earth elements. The company also developed ERSM and SRM motor samples as part of its ongoing work on magnet-free motor technology. These initiatives are aimed at reducing dependence on critical materials while supporting the evolution of efficient electric propulsion systems. In addition, Sona Comstar developed a 2 kW hub motor integrated with a controller, further expanding its portfolio of electric drive solutions.
Power Electronics and Inverter Development Progress
The company strengthened its power electronics capabilities by commissioning a Power Hardware-in-Loop system designed to emulate electric motors and qualify inverters at power levels. This capability enables more comprehensive testing and validation during product development. Sona Comstar also improved inverter efficiency through the application of Silicon Carbide MOSFET technology, a development that can contribute to enhanced performance and energy efficiency in electric vehicle powertrains.
Expansion of Indigenous Manufacturing Capabilities
During FY2026, the company completed full indigenisation of tooling while expanding several critical in-house engineering and manufacturing competencies. These capabilities now cover die design, gear design, bevel gear manufacturing, differential assembly, laser welding, gear skiving, helical gear grinding, and gearbox testing. The broader localization effort reflects the company's focus on developing advanced manufacturing expertise internally while supporting greater operational self-reliance.
Technology Independence and Long-Term Development Strategy
A notable aspect of the company's technology strategy is its continued reliance on internally developed capabilities. According to the annual report, no technology was imported during the last three years. Combined with investments in advanced motor technologies, power electronics, and manufacturing processes, this approach demonstrates Sona Comstar's commitment to building proprietary expertise and strengthening its competitive position in the evolving automotive and electrification landscape.
