Abstract
The invention relates to a fluid-cooled active part (1) for an electric machine (38), wherein the active part (1) is substantially cylindrical or hollow cylindrical, having axially extending grooves (2), at least one electrical conductor (3), which is arranged in the associated groove (2) at least in some sections and which is composed of a plurality of partial conductors (4), one or more main insulators (5), each arranged between the associated conductor (3) and the associated groove (2), and partial-conductor insulators (6), each surrounding the associated partial conductor (4). The invention further relates to an electric machine (38), having such a fluid-cooled active part (1) designed as a stator (39) and/or such a fluid-cooled active part (1) designed as a rotatably mounted rotor (40), wherein the electric machine (38) can be operated with a voltage in the range of at least a few kilovolts, preferably a few tens of kilovolts. Finally, the invention relates to a drive System (41), having such an electric machine (38) and a fluid energy machine (42) for the fluid, wherein the fluid energy machine (42) is designed as a compressor, in particular for process gas, or as a pump, in …
