Vimag Labs is building an electric motor that works without rare-earth magnets
The Bengaluru-based company replaces the permanent magnets inside an electric motor with power electronics and control software and is running pilots with vehicle manufacturers.
Vimag Labs, a Bengaluru-based company founded in September 2025 by Manish Seth and Piyush Desai, is developing an electric motor that operates without rare-earth magnets. The company's design, called the Virtual Magnet Synchronous Motor (VMSM), generates the magnetic field electronically rather than using fixed magnets. A magnetic field is created by power electronics and control software that supplies and shapes the field while the motor runs.
The motor's rotor carries windings instead of magnets, and a rotating transformer transmits power to the spinning rotor contactlessly. Vimag Labs holds five Indian patents and has applied for fifteen more, as well as several trademarks. The prototype motor runs at 6 kW continuous and 10 kW peak, producing 48 to 58 Newton metres of torque. The company aims for efficiency and performance comparable to conventional permanent magnet motors.
