Renault has revealed to the public a new EV motor,designed by its engineers and manufactured at its Cléon plant in France.

The synchronous electric motor offers 65 kW of power and 220 Nm (162 lb-ft) of peak torque, and features an integrated Chameleon charger.

New Renault's motor

The synchronous electric motor with wound rotor develops 65 kW and peak torque of 220 N·m (162 lb-ft) features an integrated Chameleon charger (the vehicle's Chameleon charger allows it to be charged via a 3kW/16A home charging box in nine hours, or in an hour by visiting a 22kW/32A three phase charging station, or in just 30 minutes from a 43kW/63A charging station).

How engineers designed this motor?

Integration, miniaturization and simplification were the three objectives that guided the design of this motor.

          * Integration: switching from macro-module stacking to fully integrated modules.

          * Miniaturization: the design of smaller modules, assembled closely (i.e., minimization of space between the modules, doing away with external power supply cables). The junction box, power electronics and Chameleon charger are all contained within a single system entitled Power Electronic Controller, enabling a 25% reduction in the size of this group of functions. Overall, Volumes have been reduced by 10% for the same level of performance, opening up new opportunities to use it for smaller vehicles.

          * Simplification: switching to air cooling for the electric motor (removal of inter-module ducting). Only the Power Electronic Controller continues to be cooled by water, adapted to its specific needs.

What has been improved?

The designers have improved the electronic management of the charging process in order to reduce charging times using low-power infrastructure (flexi-charger cable for domestic networks, 3kW and 11kW electric charging points). With this comprehensive redesign of the inverter system, the designers have been able to improve efficiency, thereby reducing the consumption of electric energy.

Production

Renault announced that their new electric vehicle motor will enter production in 2015.

Alas, more details about production were not given, but we think that future engine will be used widely.

“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.”
