48V Electric Motor

Last update: 01 Sep. 2023

What is a 48V electric motor?

The 48V eMotor (electric motor) is a reversible electric machine, which embeddes its electronic (inverter) and which is able to be integrated on all architectures beyond P0 (belt). The electrical motor can be positioned either on the input shaft of the gearbox (P2 outside, P2.5 inside), on the output shaft of the gearbox (P3) or with a gearbox (eDrive) on the rear axle drivetrain (P4).

When associated with an internal combustion engine (ICE), for hybrid applications, the 48V electric motor can provide up to 15% fuel economy benefits on WLTP cycle compared with a conventional stop-start system.

48V eMotors can also be used for eMobility (Small mobility market) associated with an adjusted gearbox (eDrive) for light electric 2-, 3- or light 4-wheelers.
