Fully Integrated Traction Motor System (E-Axle) Developed by NidecEngineering360 News Desk | April 21, 2018
Kyoto, Japan-based Nidec Corporation, a manufacturer of electric motors, has announced the successful development of a new fully integrated traction motor system (e-axle) comprising an electric motor, reduction gear box and inverter. This new system is the most advanced iteration of the company's e-axle developed to respond to the growing demand for automobile electrification.
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. The integrated design obviates the need for wiring between components, resulting in a more compact system that increases design flexibility.
The new traction motor system covers an 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.
