- Abstract
- The reliability of high temperature superconducting (HTS) racetrack coils is one of the most important factors for the development of large-scale rotating machines. However, it is necessary to investigate the stability and normal zone propagation characteristics of racetrack coils for large-scale applications such as ship propulsion motors and power generators. In this study, the quench/recovery characteristics of a racetrack-type, double pancake (DP) coil, which could be applied to HTS rotating machines, were investigated using the voltage and temperature profiles in a cryogenic conduction cooling system. The minimum quench heating flux and quench propagation velocity of the racetrack DP coil are also discussed.
