Abstract
An electric drive unit includes: a motor that rotates a rotor shaft; a housing with a bearing shield extending between motor housing and gearbox regions, the bearing shield having a first side that faces toward the motor housing region and a second side that partially defines the gearbox region and along which a channel extends; a planetary gearset including a sun gear, planet gears, and a carrier; and a wiper coupled to the housing proximate to the channel and abutting the carrier, such that fluid is wiped off of the carrier by the wiper as the carrier rotates and flows to the channel therefrom.
