Systems and methods for a leak drainage system are herein described. The leak drainage system may be implemented in an electric motor comprising a first region cooled by a liquid, a seal separating the first region from a second region, wherein the liquid does not enter the second region when the seal is not degraded, and a drainage system configured to drain liquid leaking through the seal from the first region into the second region, the drainage system comprising a radially projecting annular lip with a first angled wall positioned on a rotor shaft and an annular depression in a motor static housing circumferentially surrounding the radially projecting annular lip.

Drainage system for an electric motor

Methods and systems are provided for an electric motor. In one example, the electric motor may include a stator with end windings protruding axially, along a central axis of rotation of the electric motor, from a first end of the stator and a first end plate arranged at the first end of the stator. The first end plate may have an inner face with indentations configured to receive the end windings, the indentations including a thermally conductive material to interface with the end windings. In addition, the first end plate may include at least one cooling channel for flowing a coolant.
