Electric machine with integrated cooling and device with electric machine

An electric machine, comprising:

• a rotor including a hollow shaft, an impeller, and a cooling disk, the cooling disk arranged between a first end of the hollow shaft and the impeller;
• a stator that defines one or more fluid channels;
• and
• a first fluid space in which the cooling disk is rotatably arranged,
• wherein the hollow shaft, the cooling disk, the first fluid space, and the one or more fluid channels define a cooling circuit, and
• wherein, as a result of rotation of the rotor, the cooling disk is configured to draw in fluid through the hollow shaft and convey the fluid through the cooling disk, the first fluid space, and through the one or more fluid channels.
