Vimag Labs has raised $5 million in a Series A funding round, just four months after its September 2025 inception, to commercialize an electric motor that does not use rare-earth permanent magnets. This addresses a supply chain heavily dominated by China, which controlled 94% of global sintered magnet production as of 2024, according to IEA data. The Bengaluru-based startup's Virtual Magnet Synchronous Motor (VMSM) replaces fixed magnets in conventional Permanent Magnet Synchronous Motor (PMSM) rotors with real-time software and power electronics, synthesizing the rotor magnetic field on demand.
The core architecture, detailed in a July 8 patent titled "A Robust Rotating Transformer Excited Synchronous Motor and Its Control," retains a brushless, slip-ring-free mechanical design while eliminating the approximately 1.5 kg of rare-earth magnets found in a typical EV, as per industry data from ThunderSaid Energy. Vimag's portfolio includes five granted patents, ten pending, and fifteen trademarks, covering motor topology, control algorithms, power electronics, and specific applications. The company claims its platform matches or exceeds permanent-magnet torque and efficiency, though this has not been independently verified at scale.
Accel led the funding round, with Chakra Growth Fund and Thinkuvate participating. Vimag plans to use the capital for pilot scale-up and manufacturing expansion, currently testing with two-wheeler and passenger-vehicle OEMs and having signed a manufacturing MoU with Jendamark. The agreement does not guarantee production lines. Vimag is also targeting industrial drive systems from 200 kW to 600 kW, as well as robotics, defense, and advanced cooling. The company is scaling operations in India, Europe, and the United States.
The funding comes amid tightening physical supply chains. In April 2025, China imposed export controls on seven heavy rare-earth elements and related magnets, leading to Western automakers reducing production targets and increased licensing costs. Despite this, no mass-production alternative has emerged. Tesla's rare-earth-free motor, announced in 2023, has no confirmed production date; Valeo's magnet-free iBEE is scheduled for 2028; and Niron Magnetics, backed by GM and Stellantis, is using iron-nitride magnets instead of eliminating permanent magnets.
The challenge for Vimag is transitioning from patent to automotive qualification. The company's claim that software-defined fields can match magnet-based torque density is unverified at scale, and moving from pilot to volume production requires extensive thermal cycling, NVH validation, and cost-down engineering. A $5 million Series A provides development runway but not supply chain security; the Jendamark MoU indicates intent rather than capacity or yield data. Adopting Vimag's platform would require requalifying inverters, thermal management, and control loops—a significant undertaking that only makes sense if efficiency is maintained across temperature and load cycles at scale.
