Renault Rare-Earth-Free Motors

TL;DR

Renault is ditching permanent magnets for wound-rotor tech to dodge the supply chain mess of rare earth minerals.

Who is this actually for?

EV manufacturers and industrial engineers looking to decouple their hardware from the volatile neodymium market.

The Good

• Lower raw material costs by removing dependency on expensive rare earth magnets.
• Significantly better recyclability at the end of the vehicle lifecycle compared to traditional EV motors.

The Catch (Potential Downsides)

Wound-rotor systems are traditionally bulkier and require more complex power electronics to manage current delivery effectively.
