An axial bearing device includes an annular electrical sheet arrangement having individual sheets which protrude radially outward. In addition, an electrical coil is provided in the axial bearing device and is inserted into the electrical sheet arrangement to generate a magnetic field in the electrical sheet arrangement. The electric sheet arrangement includes at least two concentric electrical sheet rings. All adjacent electrical sheets of each electrical sheet ring substantially abut at the inner circumference of the respective electrical sheet ring.

Axial bearing device having increased iron filling

The invention relates to a drive system having at least one electrical direct drive and at least one bearing module, wherein the bearing module has a radial bearing and/or an axial bearing, and wherein the electrical direct drive and the bearing module have a cooling device.

Drive system

In order to improve the cooling of an electrical machine, the invention proposes an electrical machine having a stator () and a rotor, wherein the stator () has a cooling jacket () over at least part of the stator (), wherein the cooling jacket () has a motor jacket () surrounding the stator () and an outer jacket (), at least sections of which are spaced apart from said motor jacket (), and a hollow helix () is arranged in the section between the motor jacket () and the outer jacket () and has a predeterminable pitch (), and wherein the inlet () and the outlet () of this cooling jacket () are located substantially on an axial plane of the electrical machine.
