Abstract :
An electrical summary of a 2-pole, 900 kAT, 5000 HP compact superconducting propulsion motor with YBCO rotor windings and liquid nitrogen cooling with a power density of 3750 kVA/m3 is presented. This is a retrofit to the field of the 5.0 Tesla superconducting turbine generator built with a Nb-Ti conductor. The paper presents the electrical machine design and preliminary certification tests of the 5.0 kV air-core stator winding
