What is Valeo 3-in-1 electric Axle?

The 3-in-1 eAxle (electric Axle) is the combination of an electric motor, inverter and reducer in shared packaging. It is the heart of the powertrain. The eMotor, the inverter and the reducer are highly integrated together with shared housing design: this is a compact solution for electric vehicle and electrically-driven secondary axle in hybrid vehicles. Compare with standalone solution, 3-in-1 electric axle saves space and cost.
