The invention relates to a wind turbine with a generator and a method of assembling a generator thereof, wherein the generator comprises a rotor rotatably arranged relative to a stator. The rotor comprises a plurality of superconducting pole units arranged on a back iron which is spaced apart from a rotor structure by a number of thermally insulating plates or beams. Said plates or beams are located between either ends of the rotor and orientated relative to the rotational direction of the rotor. Each plate has a first end firmly connected to another first beam extending in an axial direction and a second end firmly connected to another second beam also extending the axial direction. The first beams are further firmly connected to the back iron while the second beams are further firmly connected to the rotor structure. The thermally insulating plates or beams provide a flexible and cheap support interface that is able to adapt to the tolerances of the individual components.
