Abstract:
The invention relates to an electric machine (100) comprising a stator (107) and a rotor (101), wherein the rotor (101) comprises a hollow shaft (102), wherein a closed hollow space (103) is formed by means of the hollow shaft (102), wherein the closed hollow space (103) is provided for receiving a cooling agent, wherein a three-dimensional transport structure (200) is provided in the closed hollow chamber (103) for transporting the cooling agent. The three-dimensional structure can, for example, be produced by means of applying an adaptive material.
