Abstract

Powertrain, comprising an inverter unit comprising an inverter configured for converting direct current to alternating current and an inverter housing defining an inverter housing interior volume accommodating the inverter, and an electric motor comprising a rotor and a stator, the rotor defining a motor axis and the electric motor being configured for providing torque, and an electric motor housing, and a reducing gear unit comprising a reducing gear and a reducing gear cover surrounding the reducing gear, the reducing gear defining an output reducing gear axis, wherein the output reducing gear axis is parallel to the motor axis, and in that the reducing gear cover and the inverter housing are arranged at opposite ends of the electric motor with respect to the motor axis, and in that the inverter housing comprises a cut-out, wherein the cut-out defines a cut-out region fully contained within the convex hull of the inverter housing, wherein the cut-out region is disjoint from the inverter housing interior volume, and in that the output reducing gear axis passes through the cut-out region without passing through the inverter housing interior volume. Inductive charging module may be …
