Nidec rolls integrated traction system
Electric motor manufacturer Nidec Corp. (Kyoto, Japan) has introduced a fully integrated traction motor system (e-axle), comprising an electric motor, reduction gear box and inverter. The system combines high torque with a low-weight design.

In addition to integrating the inverter, a separate component in Nidec’s first e-axle design announced in September 2017, the torque output capability has also been improved; the lightweight system weighs in at only 83 kg while achieving a maximum power output of 150 kW and a maximum torque output of 3,900 Nm. Furthermore, the new fully integrated design obviates the need for wiring between components, resulting in a more compact system that increases design flexibility.

The traction motor system covers a wide array of applications, ranging from compact cars to SUV platforms, and is compatible with AWD vehicles due to an optional clutch mechanism that can be disengaged when only two of the wheels need to be powered. Production is scheduled to begin in 2019, starting in China and later expanding globally.
