Software Magnets Power India's Electric Future

Vimag Labs, a startup from Bengaluru, has developed a groundbreaking technology for electric vehicle (EV) motors that eliminates the need for rare earth minerals. This innovation addresses the global supply chain vulnerabilities, particularly China's near-monopoly on these critical resources.

The company's solution, dubbed a "software-defined magnet," replaces traditional permanent magnets with precisely arranged copper coils and steel. This configuration is then activated and controlled by custom algorithms and firmware.

This proprietary architecture wirelessly transfers power within the motor, converting copper coils into dynamically adjusted electromagnets. This dynamic control allows for performance comparable to, or even exceeding, conventional permanent magnet synchronous motors (PMSMs).

Furthermore, the software-defined nature enables on-the-fly adjustments and over-the-air (OTA) updates, improving motor performance and efficiency over time without hardware changes. This also leads to a slightly extended driving range, reducing battery costs for manufacturers.

The technology is particularly significant for India, reducing its reliance on rare earth imports and leveraging its growing electronics manufacturing capabilities. Vimag Labs has secured its fifth Indian patent for this Virtual Magnet Synchronous Motor (VMSM) platform.

Currently, Vimag is focusing on electric two- and three-wheeler ecosystems and is in discussions with major manufacturers. They are also exploring integration into premium European and American electric cars and have begun prototyping for electric trucks and heavy buses.

The company is scaling production, expecting to ship between 1,000 and 10,000 motors by the end of 2026. Vimag Labs is also developing its own Application-Specific Integrated Circuit (ASIC) to further reduce costs and eliminate secondary supply chain bottlenecks.
