Vimag Labs secures patent for India’s first software-defined, magnet-free motor platform
Fifth patent granted to the Accel-backed deep-tech company, protecting the core architecture of its Virtual Magnet Synchronous Motor (VMSM).
Vimag Labs has been granted its fifth patent in India. The patent, titled “A Robust Rotating Transformer Excited Synchronous Motor and Its Control,” covers the foundational motor architecture of the company’s proprietary Virtual Magnet Synchronous Motor platform.
Unlike conventional Permanent Magnet Synchronous Motors, which rely on fixed rare-earth magnets embedded in the rotor, VMSM generates and controls its magnetic field in real time using power electronics and proprietary control algorithms. The result is a brushless, slip-ring-free synchronous motor designed to match or exceed the performance of permanent-magnet solutions—without using magnets.
The latest grant takes the company’s intellectual-property portfolio to five patents granted, ten in the pipeline and fifteen trademarks filed. The portfolio spans motor architecture, software controls, power electronics and application-specific implementations.
Commercial deployment
The patent strengthens Vimag Labs’ competitive position as it scales commercial deployments. Active pilots are under way with established two-wheeler and passenger-car manufacturers. Expansion is planned into light commercial vehicles, commercial vehicles and high-power industrial systems ranging from 200 kW to 600 kW.
Additional application areas under development include robotics, defence and cooling systems.
For OEMs, the platform is intended to provide two strategic benefits: lower motor cost potential and freedom from rare-earth-magnet supply-chain risk. For India, the technology supports indigenous development of critical electric-motor capability and the objectives of Make in India and Atmanirbhar Bharat.
“Our long-term vision is to build scalable, software-driven, magnet-free motor systems for global electrification. This innovation strengthens India’s deep-tech base across electric mobility, power electronics, robotics, defence and clean-energy systems,” Seth added.
Funding and partnerships
Vimag Labs recently raised USD 5 million in its Series A round led by Accel, with participation from Chakra Growth Fund and Thinkuvate. The company has also signed a manufacturing memorandum of understanding with Jendamark Pvt. Ltd. to support VMSM production scale-up.
