ELECTRICAL MACHINE AND METHOD FOR OPERATING IT

摘要

Electrical machine (1) comprising, as components, a stator (3) and a rotor (4) which can be rotated in relation to the stator (3), wherein the poles (14) of one component, in particular of the rotor (4), comprise superconducting coils (6) for generating a magnetic flux, wherein at least one high-temperature superconducting material block (7, 8, 9) with a heating means (10, 11, 12), which is associated with said high-temperature superconducting material block and is designed to temporarily increase the temperature of the high-temperature superconducting material block (7, 8, 9) above the critical temperature of the material of the high-temperature superconducting material block (7, 8, 9) in the superconducting coil (6), is arranged in the path of the magnetic flux.
