System having an electric machine with a cryogenic component, and a method for operating the system

A system comprising:

• a cryogenic electric machine having a multiplicity of components and a conduction system for conducting a coolant to and between the components;
• and
• a consumer configured to put an operating medium into effect,
• wherein the multiplicity of components of the electric machine comprise:
• a cryogenic component;
• a first cooling system assigned to the cryogenic component and to which the coolant is configured to be supplied in a liquid state via a first portion of the conduction system to cool the cryogenic component, using at least a portion of a vaporization enthalpy of the liquid coolant, to a cryogenic temperature;
• a further component;
• and
• a second cooling system assigned to the further component and to which the coolant is configured to be supplied by the first cooling system via a further portion of the conduction system to cool down the further component, using a remaining cooling capacity of the coolant and using at least a portion of a heating enthalpy of the coolant, to an operating temperature which is reduced in relation to ambient temperature,
• wherein the operating medium of the consumer is the coolant, and
• wherein the consumer and the electric machine are fluidically connected to each other in such a manner that the coolant, after passing through the electric machine, is configured to be supplied to the consumer in a gaseous state.
