Problems solved by technology

[0004] The heat-insulating torsion structure in the related art is a cylinder made of fiberglass, which is connected to other parts of the shaft system at both ends of the cylinder, but after a period of use, due to creep and buckling in local areas, the accuracy of size and shape will be reduced. Lost, the entire torque tube structure fails and needs to be replaced as a whole, which will increase the maintenance cost of the superconducting motor

Description

technical field [0001] The invention relates to the technical field of superconducting power applications, in particular to a superconducting motor rotor shaft heat insulation and torsion transfer structure and a design method for the superconducting motor rotor shaft heat insulation and torsion transfer structure. Background technique [0002] With the emergence of fossil energy crisis and environmental problems, the development of renewable clean energy has become a consensus. In recent years, wind energy, as a clean energy, has developed rapidly around the world, and the total installed capacity and stand-alone capacity of wind farms have continued to hit new highs. Due to its extremely high power density, superconducting motors will have advantages in both performance and cost when applied to high-power wind turbines. [0003] Since the generator rotor is in an extremely low temperature working environment and needs to transmit high torque to the outside at the same tim...
