Renault previews new EV motor


Renault has previewed a new EV motor that it says will enter production in 2015. The synchronous electric motor offers 65 kW of power and 220 Nm (162 lb-ft) of peak torque, and features an integrated Chameleon charger.
Renault designed the new motor with integration, miniaturization and simplification in mind. It uses smaller and fully integrated modules, assembled closely together to minimize the need for power supply cables. The junction box, power electronics and Chameleon charger are all contained within a single Power Electronic Controller. Overall, the size of the motor has been reduced by 10%, while retaining the same level of performance. The motor is now air-cooled, although the Power Electronic Controller still has a liquid cooling system.
The designers improved the efficiency of the charging management process, reducing the consumption of energy and improving charging times.
“The future of mobility calls for the same command of electric motor technology as it does of internal combustion engines,” said Rémi Bastien, Renault’s Director of Innovation Engineering. “We are consequently active on every front, from internal combustion engines to electric motors and alternative energies.”
