The two companies will collaborate to develop electrostatic drive motors for electric vehicle (EV) applications. Serial production is expected to start in 2026.

Sona BLW Precision Forgings Ltd on Thursday 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 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 e-mobility drivetrains and multimegawatt generator 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.
