Bengaluru-based deep-tech company Vimag Labs has secured its fifth patent in India for its proprietary Virtual Magnet Synchronous Motor (VMSM) platform, strengthening its intellectual property portfolio as it advances commercial deployment of software-defined electric motor technology. The newly granted patent covers the core architecture of a magnet-free synchronous motor that uses power electronics and proprietary control algorithms instead of rare-earth permanent magnets. The company said the technology is being piloted with two-wheeler and passenger vehicle manufacturers, with expansion planned into commercial vehicles, industrial applications, robotics and defence. Backed by Accel, Vimag Labs recently raised USD 5 million in a Series A funding round and has entered into a manufacturing agreement with Jendamark Pvt. Ltd. to support production as it scales operations in India and overseas.
Vimag Labs has been granted its fifth patent in India for its proprietary Virtual Magnet Synchronous Motor (VMSM) platform, marking another milestone in the Bengaluru-based company's efforts to commercialise software-defined electric motor technology. The patent, titled "A Robust Rotating Transformer Excited Synchronous Motor and Its Control", protects the core architecture of the company's magnet-free synchronous motor platform.
According to Vimag Labs, the patented technology differs from conventional Permanent Magnet Synchronous Motors (PMSMs), which depend on rare-earth permanent magnets embedded within the rotor. Instead, the company's VMSM platform generates and controls the magnetic field in real time through power electronics and proprietary software algorithms, eliminating the need for permanent magnets while retaining a brushless and slip-ring-free motor design.
The company said the technology is designed to deliver performance comparable to or exceeding that of conventional permanent magnet motors while reducing dependence on rare-earth materials, most of which are sourced from China. It added that the platform supports India's Make in India and Atmanirbhar Bharat initiatives by enabling the domestic development of critical electric motor technologies.
With the latest patent, Vimag Labs' intellectual property portfolio now comprises five granted patents, 10 patent applications under examination and 15 trademarks covering motor architecture, software controls, power electronics and application-specific technologies.
The company stated that the patent further strengthens its commercial strategy as it expands industry deployments. Vimag Labs is currently conducting pilot projects with established two-wheeler and passenger vehicle manufacturers. It also plans to extend the platform to light commercial vehicles, commercial vehicles and industrial systems with power capacities ranging from 200 kW to 600 kW. Additional applications under development include robotics, defence and cooling systems.
Commenting on the development, Manish Seth, Co-founder and Chief Executive Officer of Vimag Labs, said the patent reflects more than 87,600 engineering hours invested in developing the technology. He stated that the intellectual property would reinforce the company's commercial roadmap, including original equipment manufacturer (OEM) partnerships, technology licensing, manufacturing expansion and future business growth.
Seth added that the company's long-term objective is to develop scalable, software-driven, magnet-free electric motor systems for global electrification while strengthening India's capabilities in deep technology across electric mobility, power electronics, robotics, defence and clean energy applications.
The patent follows Vimag Labs' recent USD 5 million 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 scale-up of VMSM production.
Founded in Bengaluru, Vimag Labs is developing electric motor technologies for mobility, industrial and defence applications and is expanding its operations across India, Europe and the United States.
