New EV motor avoids rare earths

A new-generation automotive electric motor will be developed and made in France under a Renault Group, Valeo and Valeo Siemens eAutomotive agreement.

All have signed a memorandum of understanding (MoU) to form a strategic partnership on the electric motor, eliminating the use of rare earths and offering more power on less energy.

Each of the partners will contribute to the development and production of two key parts of the electric motor – the rotor and the stator.

Renault will develop and produce the electrically excited synchronous motor (EESM) rotor technology, offering 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, based on Valeo’s technological expertise in copper wire assembly, reportedly able to generate more power without having to use more electrical energy.

The partnership expects to be the first to mass produce a 200kW electric motor without using rare earths, starting in 2027.

“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,” Renault Group chief executive Luca de Meo says.

Valeo chief executive Christophe Périllat says the partnership will result in a major step forward for electric mobility.

“This new motor will meet the most stringent environmental requirements and the highest performance standards.”

Meanwhile, an updated Renault, Nissan and Mitisubishi Alliance will focus on pure EVs and connected mobility.
