Drainage system for an electric motor

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.

A method for an electric motor, comprising:

• rotating a shaft;
• driving liquid via an angled, annular projection of the shaft;
• capturing driven liquid via a channel in a housing of the electric motor;
• and
• directing liquid out of the channel via a drain hole.
