Abstract
A wind turbine includes a dynamoelectric machine including a liquid-cooled stator and a rotor interacting with one another. The stator includes a magnetically conductive body and a winding system which is embedded in slots of the magnetically conductive body and which includes a main insulation arranged between a conductor of the winding system and a slot wall and including at least one recess provided in a cooling-channel impression of the main insulation to form at least one axial cooling channel extending between the main insulation and the slot wall, so that the at least one cooling channel borders the slot wall without insulation in direct contact with the slot wall. The winding system includes end windings which are also liquid-cooled. A can separates the stator and the rotor from one another and enables different cooling media for the stator and the rotor.
