Abstract
Systems and methods for cooling an electric motor in an electric drive unit are provided. In one example, the electric drive unit includes electric motor with a housing with a water jacket arranged therein, a stator that includes a plurality of stator laminations positioned within the housing, and an oil inlet mounted to and extending through the housing. The plurality of stator laminations includes a radial opening that is designed to receive oil from the oil inlet and direct oil to one or more oil ducts that axially extend through at least a portion of the plurality of stator laminations.
