Description

technical field [0001] The invention relates to a high-temperature superconducting motor magnet performance test device, which belongs to the technical field of measurement and testing. Background technique [0002] The high temperature superconducting motor magnet is used as the excitation winding in the motor and is a major component of the high temperature superconducting motor. Under normal circumstances, several superconducting magnets on the rotor are located in a vacuum container formed by welding. Due to the poor mechanical properties of high-temperature superconducting materials, the performance will be greatly reduced if there is a slight carelessness during the processing of the magnets. Therefore, Before the magnet is installed, the performance of the magnet should be tested to confirm that it can generate the designed air gap magnetic field when it is working, so as to avoid troublesome rework caused by installing unqualified magnets. [0003] Critical current...
