1. An arrangement to ensure an air gap in an electrical machine, comprising:
an electrical machine with a stator arrangement and a rotor arrangement, the rotor arrangement rotating around a longitudinal axis, wherein: parts of the rotor arrangement interact with parts of the stator arrangement to generate electrical power, an air gap is defined by a distance between the parts of the rotor arrangement and the parts of the stator arrangement, the parts of the stator arrangement are opposite to the parts of the rotor arrangement along a certain length, a cross section of the air gap changes along the certain length such that the air gap is not uniform in view to the referred certain length, the stator arrangement comprises a lamination stack which is constructed to support at least one winding of a stator-coil, the rotor arrangement comprises a plurality of permanent magnets, the cross section of the air gap is configured by a change in a shape of the lamination stack along the certain length, the stator arrangement and the rotor arrangement are connected via a single main bearing, the stator arrangement comprises a stator support structure and a lamination stack, the lamination stack is constructed to support the winding of the stator-coil, the stator support structure comprises support elements for a two-sided support of the lamination stack, the support elements being ring-shaped and connected via the single main bearing to the rotor arrangement, outer ends of the ring-shaped support elements are attached to a hollow cylindrical support element, and the hollow cylindrical support element carries the ring-shaped lamination stack and the winding. |
