Abstract

Powertrain, including an inverter unit, inverter housing, electric motor, electric motor housing, and a reducing gear. The inverter unit having an inverter configured for converting direct current to alternating current. The inverter housing defining an inverter housing interior volume accommodating the inverter. The reducing gear unit has a reducing gear and a reducing gear cover surrounding the reducing gear. The reducing gear defines an output reducing gear axis that is parallel to the motor axis. The reducing gear cover and the inverter housing are arranged at opposite ends of the electric motor with respect to the motor axis. The inverter housing includes a cut-out that defines a cut-out region fully contained within a convex hull of the inverter housing, wherein the cut-out region is disjoint from the inverter housing interior volume. The output reducing gear axis passes through the cut-out region without passing through the inverter housing interior volume.
