Read more about Renault and Valeo’s rare-earth-free motor technology here.
Renault Group is partnering with Valeo to develop a unique, new electric motor that uses no rare earth elements — the E7A. Renault is providing the rotor and Valeo is offering the stator, and both companies are contributing their expertise in technology development and production.
Rare earth elements, such as Neodymium and Dysprosium, are generally used in permanent magnet motors in EVs.
By using a wound rotor instead of permanent magnets, Renault is improving the engine’s output, securing its supply chain and sustainability by requiring no rare earth magnets.
The result is expected to be even more powerful and efficient than previous electric motor models.
Renault pioneered electrically excited synchronous motors (EESM) when it introduced the ZOE in 2012. This is also the third motor generation in partnership with Valeo. In 2022, Valeo further refined the EESM with the launch of a hairpin stator. Both companies are proud of their new E7A, which is currently in the prototype phase, with a full debut set for 2027.
