Renault , Valeo and Valeo Siemens eAutomotive have signed an MoU to form a partnership for the design, co-development and manufacture in France of a new-generation automotive electric motor, eliminating the use of rare earths.
The three partners will combine to design an electric powertrain system offering more power using less energy, without the use of rare earths.
Through, the 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.
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 experience, 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 experience in copper wire assembly. Using a higher density of copper in the stator, Valeo is able to generate more power without resorting to more electrical energy.
Renault Group, Valeo and Valeo Siemens eAutomotive note they 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’s Cléon plant in Normandy, France.
“Together, we will design and develop a new generation of high-tech electric motors, produced at our Cléon plant,” said Renault CEO, Luca de Meo.
“This partnership is further demonstration of our capacity to be at the forefront of the electric revolution taking place in the automotive industry and to anchor the new automotive value chain in France.”
For his part, Valeo CEO, Christophe Périllat, added: “This strategic partnership will result in a major step forward for electric mobility. Alongside Renault Group, we are creating a new-generation automotive electric motor that eliminates the use of rare earths.
“This new motor will meet the most stringent environmental requirements and the highest performance standards.”
