- Vimag Labs secured its fifth Indian patent for a Virtual Magnet Synchronous Motor that generates rotor magnetic fields in real time using power electronics and proprietary algorithms, eliminating the fixed rare-earth magnets used in standard PMSM EV motors.
- The Bengaluru startup raised a $5 million Series A led by Accel, with Chakra Growth Fund and Thinkuvate participating, and signed a manufacturing MoU with Jendamark targeting 200 kW to 600 kW industrial systems plus robotics, defense, and cooling applications.
- Co-founder and CEO Manish Seth said the patent represents over 87,600 engineering hours; Vimag now holds five granted patents with ten more patents and fifteen trademarks in the pipeline.
- China controls roughly 91% of global rare-earth refining and 94% of sintered permanent-magnet production per 2024 IEA data, and its April 2025 export controls on seven heavy rare-earth elements forced US and European automakers to trim production.
- Beijing's October 2025 "0.1%" de minimis rule targeting foreign-made products with Chinese rare-earth content was suspended on November 7, 2025 for one year as part of a broader trade truce — paused but not gone.
- Tesla announced a rare-earth-free next-gen motor at its 2023 Investor Day with no production date confirmed, while GM and Stellantis are backing Niron Magnetics' iron-nitride "Clean Earth" magnets and Valeo's magnet-free iBEE motor isn't slated for commercialization until 2028.
Why it matters: Automakers remain exposed to China's rare-earth processing choke point: Beijing controls 91% of refining and 94% of magnet output despite holding only a third of reserves, and the November 7, 2025 one-year suspension of its October de minimis expansion leaves the squeeze one diplomatic stumble away from snapping back — with no Western magnet-free drive unit yet in mass production to absorb the hit.
