1. An electric drive unit, comprising:
a motor that drives rotation of a rotor shaft;
a housing that includes a bearing shield that extends between a motor housing region that houses the motor and a gearbox region, the bearing shield having a first side that faces toward the motor housing region and a second side opposite the first side that partially defines the gearbox region and along which a channel extends;
a planetary gearset disposed within the gearbox region and including a sun gear operably coupled with the rotor shaft such that the sun gear and the rotor shaft are configured to rotate together at a common rate of rotation about an axis, a plurality of planet gears that interface with the sun gear and are configured to revolve around the axis, and a carrier that is operably coupled with the plurality of planet gears, such that revolution of the planet gears rotates the carrier about the axis; and
a wiper coupled to the housing proximate to the channel and configured to abut the carrier, such that fluid is wiped off of the carrier by the wiper as the carrier rotates and flows to the channel therefrom.
