Abstract

A wind turbine with a wind turbine tower; a nacelle; a wind turbine rotor hub having at least one blade mounted thereon; a shaft coupled to the wind turbine rotor hub, and to a generator which has a rotor with at least one superconducting rotor coil and a stator with at least one conductive stator coil. The rotor coil and the stator coil have interacting magnetic fields for inducing current in the stator coil. A stator iron and at least a part of the stator coils are thermally coupled by first and second types of cooling channels along an inner and an outer periphery of the stator iron, respectively. The cooling channels guide a coolant that conducts heat away from the stator coil. Interconnecting pipes are coupled to at least a first chamber or a second chamber of the second type of cooling channels.
