Axial Type Flat Disc Slip Rings Arrangement For High Temperature Superconducting Synchronous Machine
Abstract: The invention relates to the Described herein is a system for high temperature superconducting (HTS) synchronous machine comprises a positive excitation axial type flat disc slip ring (506) and a negative excitation axial type flat disc slip ring (508) configured via fastening means (502) to a non-drive end (NDE) shaft flange (501). The two concentric axial type flat disc shaped slip-ring arrangement (506, 508), thereby eliminating typical slip-ring shafts and reducing the overall length and weight of HTS rotor. A plurality of current leads (507A, 507B) positioned in a high temperature superconducting (HTS) rotor connect the superconducting pole coils to the slip ring assemblies (506, 508) through an at least one cryogenic current feed through (509A, 509B). The reduced length of HTS rotor also have enhanced cryogenic performance because of reduced heat loads on cryocooler. The slip-ring assemblies (506, 508) are electrically isolated from main shaft and prevent any deterioration in vacuum of HTS rotor.
