Vimag Labs has been granted its fifth patent in India. Titled “A Robust Rotating Transformer Excited Synchronous Motor and Its Control”, the patent covers the foundational motor architecture of the company’s proprietary Virtual Magnet Synchronous Motor (VMSM) platform.

Unlike conventional Permanent Magnet Synchronous Motors (PMSMs), which rely on fixed rare-earth magnets embedded in the rotor, the 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 that matches or exceeds the performance of permanent magnet solutions without using magnets.

The latest grant takes the company’s intellectual property portfolio to five granted patents, ten patents in the pipeline and 15 trademarks filed across motor architecture, software controls, power electronics and application-specific implementations.

The patent strengthens Vimag Labs’ competitive position as it scales commercial deployments. The company currently has active pilots under way with established two-wheeler and passenger car manufacturers, with plans to expand into light commercial vehicles, commercial vehicles and high-power industrial systems ranging from 200 kW to 600 kW (0.2 MW to 0.6 MW). Additional applications under development include robotics, defence and cooling systems.

For original equipment manufacturers, the platform offers two key advantages: lower motor costs and reduced exposure to the supply-chain risks associated with rare-earth magnets, the majority of which are currently sourced from China. For India, the technology supports the Make in India and Atmanirbhar Bharat objectives by enabling the indigenous development of critical electric motor technology.

“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,” said Manish Seth, Co-founder and CEO, Vimag Labs. “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,” he further added.

Vimag Labs recently raised USD 5 million in its Series A funding 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 the production scale-up of its VMSM platform.
