Nidec presents integrated e-axle system

Nidec e-axle

First production is scheduled in 2019 in China, with international expansion to follow

Nidec, a Kyoto-based manufacturer of electric motors, has developed a fully integrated traction motor system (e-axle) consisting of an electric motor, reduction gear box and inverter.

The system weighs 83 kg and can achieve a maximum power and torque outputs of 150 kW and 3,900 Nm, respectively. The fully integrated design does not require wiring between the components which makes the system more compact and flexible, Nidec says.

The e-axle has multiple applications from compact cars to SUV platforms, while an optional clutch mechanism also makes it compatible with AWD vehicles. This clutch feature can be disengaged when only two of the wheels need to be powered.

Nidec’s first e-axle design was announced in September 2017.

Last year the manufacturer also announced plans to cooperate with France’s PSA Groupe in the development of traction motors for electrified vehicles including mild-hybrids battery EVs and PHEVs. The two agreed to set up a new business unit headquartered in Carrières sous Poissy, France, with a production site in Trémery, which woudl supply motors to PSA and other OEMs.
