Renault Group, Valeo and Valeo Siemens eAutomotive join forces…to produce a new electric motor

When testing the Arkana Hybrid, we already mentioned the clever way Renault sources know how and expertise across boundaries. With the electric age coming upon us, further cooperation is growing to develop and produce ever more efficient drivetrains, using ever less resources. The news came that Renault is now joining forces with Valeo and Siemens… interesting!

Indeed, Renault Group, Valeo and Valeo Siemens eAutomotive have signed on February 10th a memorandum of understanding to form a strategic partnership for the design, co-development and manufacture in France of a new-generation automotive electric motor, eliminating the use of rare earths.

Under this partnership, each of the three partners will contribute to the development and production of the two key parts of the electric motor: the rotor and the stator.

Overall architecture comes from Renault…

Renault will develop and produce the EESM (electrically excited synchronous motor) rotor technology, designed without the use of rare earths, it offers enhanced energy performance.

In addition to the supply of components based on each company’s best expertise, the overall architecture of the all-in-one motor for Renault Group will also be designed by Renault.

Valeo and Valeo Siemens eAutomotive will develop and produce the stator, which is based on Valeo’s technological expertise in copper wire assembly. Thanks to its unique know-how in this field, which allows it to use a higher density of copper in the stator, Valeo is able to generate more power without having to use more electrical energy.

Renault Group, Valeo and Valeo Siemens eAutomotive will be the first to mass produce a 200kW electric motor without using rare earths, starting in 2027. Production of the motor for the automaker’s own needs will be based at Renault Group’s Cléon plant in Normandy, France.

More Renault news soon!
