  • the electromagnetically effective air gap between the rotor and the stator can be arranged on a comparatively large diameter, whereby the machine can be designed to be of short axial construction while nevertheless achieving a high torque.
  • the electronic assembly can be accommodated in the interior of the electrical machine.

  • This annular space is thus limited at least by the first cylinder region of the fluid-cooling arrangement.
  • a bottom region and a second cylinder region formed radially spaced from the first cylinder region may be present.
