System for cooling an electrical machine

摘要

A system for cooling an electrical machine (10), wherein the electrical machine (10) comprises a stator (12) having a plurality of coils (24). The stator (12) defines an axial bore (14) configured to receive a rotor. An exterior housing (30) has axial ends (36), wherein the exterior housing (30) defines an axial bore (34) configured to receive the stator (12). An end cap (50) is configured to couple to at least one of the axial ends (36) of the exterior housing (30), wherein the end cap (50) includes a fluid inlet (60) configured to receive a liquid coolant. The end cap (50) includes a plurality of fluid outlets (66), wherein at least one of the plurality of fluid outlets (66) is configured to deliver the liquid coolant from the fluid inlet (60) to at least one of the plurality of coils (24).
