Sona BLW Precision Forgings Ltd partnered with C-Motive Technologies (C-Motive), the technology company that has developed the world’s first commercially viable electrostatic motor. Sona Comstar and C-Motive will collaborate to develop electrostatic drive motors for electric vehicle (EV) applications. Serial production is expected to start in 2026, the company said in a release.
The proposal, amongst others, involves participation in C-Motive’s latest financing round. According to the company C-Motive’s product is a reinvention of the electric motor. Traditional electric motors use electromagnetic forces to convert electric power to mechanical power. C-Motive’s product harnesses the power of static cling to liberate engineers and designers from permanent magnets and active cooling, the company added. C-Motive’s electrostatic machines deliver high torque and ultra-high efficiency at low speeds without using rare earth metals or permanent magnets.
C-Motive’s electrostatic machine technology can be scaled from a single kilowatt to tens of megawatts, Sona Comstar said. These machines can be designed for varied purposes: small, modular torque motors for stationary applications to large, rugged machines for emobility drivetrains and multimegawatt generators for wind turbines. By limiting the use of copper and removing the need for permanent magnets, C-Motive’s technology can deliver a machine that is less price volatile and more efficient at the same time, reducing embodied carbon and carbon emissions along the way.
“We are impressed with C-Motive’s motor’s high yet ripple-free torque generation without active cooling, very little copper, and no rare earth metals or magnets. With the development of technologically superior and commercially competitive products compared to the existing electromagnetic motors, there will be a large market opportunity in the fast-growing e-mobility market,” Kiran M Deshmukh, Group CTO, Sona Comstar, said.
According to Matthew Maroon, Chief Executive Officer, C-Motive Technologies, this partnership will be able to accelerate the world’s transition to electrify mobility and do so with an efficient and environmentally sustainable product. “On behalf of the entire C-Motive team, we thank the team at Sona Comstar for their vision and hard work in putting this partnership in place. We are excited for our future together,” Maroon added.
