Quench in high-temperature superconducting motor field coils: experimental results

The results of quench tests on high-temperature superconducting motor coils are presented. These results clearly demonstrate that the quench process is characterized by a current level, referred to as the "quench current", above which the cooling system cannot maintain the winding temperature. The result will be an unstable growth in winding temperature in a process commonly referred to as a winding quench
