Abstract

A superconducting device has a rotor rotatable about an axis of rotation and a superconducting winding in a heat conducting winding carrier. The winding carrier has a central cooling agent cavity with a lateral cavity leading out of the winding carrier connected thereto. A cold head associated with a cooling unit is connected to a condenser unit which condenses the cooling agent. A fixed heat tube guiding the cooling agent is coupled to the condenser unit, protruding axially into the co-rotating lateral cavity and is sealed in relation thereto.
