Renault Group is designing a new motor that it powerful and efficient, and uses no rare earths. This third motor generation is a team adventure with Valeo, which is contributing its stator expertise. Renault Group is contributing the rotor. This new motor, E7A, is still at the prototype stage and set to debut in 2027.
The E7A all-in-one electric motor: more compact and rare-earths-free
Renault pioneered electrically excited synchronous motors (EESMs) in production vehicles when it introduced ZOE in 2012. This know-how puts it in a position to supply an all-in-one architecture for the new E7A motor (to make it 30% more compact for equivalent power than the current motors equipping the Megane E-Tech electric and the Scenic E-Tech electric) and the rare-earths-free rotor technology (to shrink its carbon footprint by 30%).
By using a wound rotor instead of permanent magnets, Renault is improving the engine’s output, securing its supply chain and avoiding reliance on countries that produce rare earths and magnets.
This third-generation motor will also help shorten battery charging times as the system will be built for 800 volts instead of 400 volts, the standard today. The stator by Valeo will boost power and efficiency. The new E7A motor, as a result, will unleash up to 200 kW. It will also supply more power without consuming more electricity. The E7A motor uses hairpin technology to assemble copper wires, a Valeo specialty since 2010.
At this stage, the motor is still under development. There are other stages to go through before it can reach serial life. The mass production of this new-generation engine will start at Renault Group’s Cléon factory at the end of 2027.
