Vimag Labs has secured its fifth patent in India, marking another step forward for its magnet free electric motor technology. The new patent, titled “A Robust Rotating Transformer Excited Synchronous Motor and Its Control,” protects the core motor architecture behind the company’s Virtual Magnet Synchronous Motor (VMSM) platform.
At the heart of the VMSM approach is a simple but powerful idea. Instead of using fixed rare earth permanent magnets embedded in the rotor, as in conventional PMSMs, Vimag’s motor generates and controls the magnetic field electronically in real time.
Advanced power electronics and proprietary control algorithms do the work that magnets normally would, enabling a brushless, slip ring free synchronous motor that can match or even beat permanent magnet performance without using any magnets at all.
With this latest grant, Vimag’s intellectual property portfolio now stands at five patents granted, ten more in the pipeline and fifteen trademarks filed. Together, they cover the full stack of the platform, from motor architecture and software controls to power electronics and application specific implementations.
The patent also arrives as Vimag ramps commercial activity. The company is already running pilots with established two wheeler and passenger car manufacturers and is planning to extend its reach into light commercial vehicles, commercial vehicles and high power industrial systems in the 200 kW to 600 kW range.
Development work is also underway in adjacent areas such as robotics, defence and advanced cooling systems, where magnet free, software defined motors can offer compelling benefits.
For OEMs, the VMSM platform promises a dual advantage. It can lower motor costs by removing expensive magnets and at the same time reduce exposure to rare earth supply chains, which are still heavily concentrated in China.
For India, the technology aligns directly with Make in India and Atmanirbhar Bharat, supporting indigenous development of critical electric motor technology for EVs and industrial applications.
On the business side, Vimag Labs recently raised 5 million dollars in a Series A round led by Accel, with participation from Chakra Growth Fund and Thinkuvate. The company has also signed a manufacturing MoU with Jendamark Pvt. Ltd. to support scaling up VMSM production, pairing its deeptech motor IP with an experienced manufacturing partner to move from pilots into volume programs.
Leadership Comment
Manish Seth, Co-founder and CEO, Vimag Labs, said: “This patent is the outcome of over 87,600 engineering hours. It strengthens every dimension of our commercial roadmap — OEM partnerships, licensing, manufacturing scale-up, and future growth.”
He added: “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.”
