Thermal performance of the rotor of the MIT-EPRI 3 MVA superconducting alternator

The MIT-EPRI 3 MVA superconducting alternator has undergone a number of successful electrical and mechanical tests. During these tests a great deal of information on the thermal performance of the rotor has been collected. This information has not been presented in the literature or discussed generally. Thermal performance data of interest to generator designers such as: helium flow circuit behavior and conceptual design, electrical lead performance following reconstruction and shield thermal performance is discussed.
