Abstract
An electric drive shaft is disclosed including at least one speed-variable generator for generating a voltage with a variable amplitude and a variable frequency, and at least one speed-variable drive motor supplied with the voltage. The drive shaft enables repercussions on the voltage during sudden load changes, and therefore the complexity of the regulation for stabilizing the voltage, to be reduced due to the generator including a supraconductor winding, especially a high-temperature supraconductor winding.
