<p>The invention relates to an arrangement to compensate a non-uniform air gap, which is located in an electric machine. The invention especially relates to a compensation of an air-gap, which is between a rotor and a stator of a generator. According to the invention the electrical machine contains a stator arrangement (108) and a rotor arrangement (114). The rotor arrangement (114) rotates around a longitudinal axis (A). At least parts (118) of the rotor arrangement interact with parts (111) of the stator arrangement to generate electrical power. The air gap is defined by the 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. The cross section of the air gap changes along this length thus the air gap is not uniform in view to the referred certain length. The flux density of magnets, which are part of the rotor arrangement, is changed in dependency to the cross section of the air-gap.</p> |
