Beschreibung
Zusammenfassung:	An electrical machine comprising a rotor 20, a stator 30 and an air gap 40 arranged between the rotor 20 and the stator 30 is provided. The stator 30 or rotor 20 comprises a plurality of electrical coils 90, wherein one or more of the electrical coils 90 carry a heat sink, wherein the heat sink is attached to the electrical coil with a thermally conductive material. Methods for modifying a temperature distribution of a stator in an electrical machine are also provided.
