The electric vehicle (EV) industry has been heavily dependent on permanent magnet motors that use rare-earth materials for high efficiency and performance. However, limited global availability, supply chain risks, and dependence on imported rare earth minerals have encouraged manufacturers to explore alternative motor technologies. In a major development for India’s clean mobility sector, Vimag Labs patents rare-earth-free EV Motor technology, introducing a software-defined, magnet-free electric motor platform designed to reduce dependence on rare-earth magnets while maintaining the performance levels of conventional permanent-magnet motors.
The Bengaluru-based deep-tech startup has secured its fifth Indian patent for its innovative Virtual Magnet Synchronous Motor (VMSM) platform, marking an important milestone in India’s efforts to build indigenous EV technologies.
Vimag Labs Secures Patent For Virtual Magnet Synchronous Motor Platform
The newly granted patent is titled “A Robust Rotating Transformer Excited Synchronous Motor and Its Control.” The patent protects the core architecture behind Vimag Labs’ proprietary VMSM technology.
Unlike traditional Permanent Magnet Synchronous Motors (PMSMs), which use rare-earth magnets embedded inside the rotor, the VMSM platform generates and manages magnetic fields through advanced power electronics, software algorithms, and intelligent control systems.
According to the company, this approach delivers similar performance benefits without requiring rare earth materials.
With this achievement, Vimag Labs patents rare-earth-free EV Motor technology that could provide manufacturers with a locally developed alternative to conventional EV motor systems.
How Vimag Labs’ Magnet-Free Motor Technology Works
Most modern electric vehicles use permanent magnet motors containing approximately 1–3 kg of rare-earth magnets. These materials play an important role in improving motor efficiency and power density, but create challenges due to limited supply sources and global mineral concentration.
Vimag Labs’ VMSM platform addresses these challenges through:
a) Zero Rare Earth Magnet Dependency
The technology eliminates the requirement for rare-earth magnets, reducing exposure to critical mineral shortages and international supply chain disruptions.
b) Software-Controlled Magnetic Fields
Instead of relying on permanent magnets, the motor dynamically creates and controls magnetic fields using proprietary software, algorithms, and power electronics.
c) Advanced Brushless Motor Design
The platform uses a brushless and slip-ring-free synchronous motor architecture, improving reliability and simplifying mechanical design.
This technology could help EV manufacturers develop more sustainable and supply-chain-independent electric powertrains.
Patent Strengthens Vimag Labs’ Growing Intellectual Property Portfolio
The latest patent expands Vimag Labs’ intellectual property base, which now includes:
- 5 granted patents
- 10 patent applications
- 15 trademarks
These patents and applications cover areas including motor architecture, software-based control systems, power electronics, and related EV technologies.
The company says the latest innovation is the result of more than 87,600 engineering hours invested in research and development.
Funding Support And Manufacturing Expansion Plans
Vimag Labs is preparing for commercial expansion with strong financial and manufacturing support.
The company recently raised USD 5 million in a Series A funding round led by venture capital firm Accel, along with participation from Chakra Growth Fund and Thinkuvate.
To support large-scale manufacturing, Vimag Labs has also signed a manufacturing Memorandum of Understanding (MoU) with Jendamark India.
The partnership is expected to help the startup move from technology development towards wider industrial deployment.
EV Manufacturers Testing Vimag Labs’ Motor Technology
The company is already conducting pilot projects with leading vehicle manufacturers in India.
Current applications include:
- Two-wheeler manufacturers
- Passenger vehicle manufacturers
The startup aims to expand the technology across multiple sectors, including:
- Light commercial vehicles
- Heavy commercial vehicles
- Industrial systems ranging from 200 kW to 600 kW
- Robotics
- Defence applications
- Advanced cooling systems
The scalable nature of the VMSM platform could make it suitable for both automotive and industrial applications.
Reducing India’s Dependence On Imported Critical Minerals
The global EV industry is looking for alternatives to rare-earth-based motors due to concerns around mineral availability and supply chain concentration.
By developing a magnet-free motor platform, Vimag Labs aims to support India’s vision of developing domestic EV technology capabilities.
The company believes its innovation can help manufacturers achieve high-performance electric mobility solutions while reducing dependence on imported rare earth materials.
The development of Vimag Labs Patents Rare Earth Free EV Motor technology represents a significant step towards building cleaner, more resilient, and self-reliant electric vehicle ecosystems.
CEO Highlights Future Growth Vision
Manish Seth, Co-founder and CEO of Vimag Labs, said that the newly granted patent represents years of engineering innovation and supports the company’s expansion plans.
He highlighted that the technology will help accelerate partnerships with original equipment manufacturers (OEMs), licensing opportunities, manufacturing growth, and wider adoption across different industries.
