Magnet-free EV traction motor
EV traction-motor architectures — externally-excited (wound-rotor) synchronous, switched-reluctance and advanced induction — that deliver competitive torque density without NdFeB rare-earth permanent magnets, removing the single largest rare-earth dependency in the EV bill of mat

Mapped relationships
- DevelopsVimag Labs- Vimag Labs develops magnet-free EV traction-motor technology.
- Depends onMotor-control power electronics- Magnet-free architectures depend on advanced motor-control power electronics — the controller carries the complexity the magnet no longer does.
- related toRare-earth permanent magnets (NdFeB)- Substitution pathway: magnet-free traction motors remove NdFeB rare-earth permanent magnets from the EV bill of materials, reducing exposure to the China-controlled magnet chokepoint.
- related toScheme to Promote Manufacturing of Sintered Rare Earth Permanent Magnets- Demand-side hedge complementary to the supply-side REPM scheme: domestic magnet manufacturing and magnet-free motor design are parallel routes to reducing rare-earth-magnet import dependence.
