Cryogenic cooling technology for HTS electric machinery

Cryogenic cooling technology for HTS electric machinery

Cryogenic cooling options for high temperature superconducting (HTS) synchronous machines are outlined. Present electric machines use multiple Gifford-McMahon (GM) cryocoolers coupled to the cold HTS field winding via convective flow of single-phase, cold helium gas or two-phase neon. Pulse tube cry...

Zusammenfassung:Cryogenic cooling options for high temperature superconducting (HTS) synchronous machines are outlined. Present electric machines use multiple Gifford-McMahon (GM) cryocoolers coupled to the cold HTS field winding via convective flow of single-phase, cold helium gas or two-phase neon. Pulse tube cryocoolers are an attractive future option due to their potential high reliability. Major performance issues include reliability, efficiency and cost
