Abstract

Methods and systems for an electric drive assembly are provided herein. In one example, an electric drive system is provided that includes two multi-motor drive units with associated planetary gear reductions that have asymmetric gear ratios. The planetary gear reduction in each drive unit includes a ring gear and a sun gear that are rotationally coupled to a pair of motors and a carrier rotationally coupled to an output gear that interfaces with a gear reduction of an axle assembly.
