Renault is looking for a Chinese supplier of rare-earth free motors, according to sources

Two sources with knowledge of the matter said that France's Renault had ended its project with Valeo for the development of a new electric vehicle motor without rare earths and was looking to find a Chinese supplier who is cheaper.

Renault, General Motors, and other automakers, as well as suppliers like ZF, BorgWare, and Valeo, have developed EV motors that do not need rare earths.

Renault announced in 2023 that it would be working with Valeo to develop a more powerful, compact, and lightweight EV motor, without rare earths. It described this as an "innovation made in France".

China controls 70% global rare earths mining, and 85% refining. Beijing's decision imposing increasing exports limits on rare earths sent the industry scrambling to find supplies.

Renault has been using rare-earth free motors since 2012. Valeo, on the other hand, brought its expertise to the stator (the fixed part that houses the rotor) by using copper wire technology.

One of the sources stated that the E7A project was no longer done with Valeo. "It is now being done in-house throughout the entire value chain except for the stator, which can be purchased from a Chinese provider."

Renault's decision not to continue Valeo's participation in the rare-earth-free motor project, and its search for a Chinese supplier with lower costs have never been reported.

Both sources stated that the move was motivated by the need to reduce costs. Chinese suppliers offered very competitive prices.

A spokeswoman from Ampere, Renault EV's subsidiary, stated that a Chinese partner was a possibility, but added that no decision had been made, and the "process is still in progress".

Valeo has declined to comment.

'MADE in France' OBJECTIVE REMAINS

The inverter, a key component of an EV, would be provided by the Franco-Italian company STMicro, even if the Chinese company contributed to the stator.

Ampere's spokeswoman stated that they are currently studying the option of placing the stator in France.

Renault, the smaller of the main legacy carmakers, has developed numerous partnerships in the past few years to manage the costs involved with developing EVs.

China is also a major supplier of electric vehicles. It developed its new electric Twingo with the help of a Chinese engineering team in only two years.

Renault will use the new motors, which are free of rare earths, to power its next generation compact EVs. This is expected to happen by 2028. The strategic plan that CEO Francois Privost will share in March will include these motors.

The E7A will be able to produce 200 kW, 25% more power than current Renault EVs such as Scenic. Its 800-volt system also allows for a faster charging time, thanks to the fact that it is double the voltage.

Valeo continues to work with German supplier Mahle on its own magnetless "iBEE", EV motor. This motor will also deliver up to 350 kW of power and be available in the market by 2028. (Reporting and writing by Gilles Guillaume; editing by Alexander Smith).
