Abstract

A cooling cap for a stator of an electrical machine of a motor vehicle is provided. The cooling cap can be fitted onto an end winding of electrical windings of the stator which project beyond an axial end of a laminated core of the stator and which cooling cap is designed as a heat sink for cooling the end winding, wherein the cooling cap is formed, at least in regions, from an electrical insulating material. A stator and a motor vehicle including the cooling cap are also provided.
