London, 31 October 2023, (Oilandgaspress) – Renault Group is taking the next step and designing a new motor that is in a class by itself worldwide, even more powerful and efficient, and uses no rare earths. This third motor generation is a team adventure with Valeo, which is contributing its stator expertise. This motor, E7A, is still at the prototype stage and set to debut in 2027.
A breakthrough from France will bring about a more powerful, more compact and cleaner electric motor: Renault Group and Valeo are combining their expertise to create a new electric motor generation. As a result of the regular conversations between the carmaker and the equipment manufacturer, this partnership that started in 2021 soon grew into a co-development journey. They each pooled one key part (Renault Group the rotor, Valeo the stator) as well as their expertise in technology development and production. The are currently fine-tuning their E7A high-tech motor.
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. And 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. And the E7A motor uses hairpin technology to assemble copper wires, a Valeo specialty since 2010.
At this stage, the engine 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.
