Electric motor cooling system and method for operation of said system

Abstract

Methods and systems for cooling an electric motor are provided. An electric motor cooling system, in one example, includes a stator with a first end winding on a first axial side, potting material at least partially enclosing the first end winding, and a plurality of coolant passages adjacent to the stator, where at least a portion of the plurality of coolant passages are adjacent to the potting material. The electric motor cooling system also includes a coolant passage housing including a plurality of fins defining a portion of the boundaries of the plurality of coolant passages and in face sharing contact with an outer surface of the stator.
