This paper describes structural features of a trial-manufactured airgap winding stator for a 50 MVA superconducting generator and results of various characteristic tests. The stator has an improved winding section, strengthened against electromagnetic force and smaller sized, due to use of a four-layer water cooled helical airgap armature winding. Peculiarities as to the flux distribution and airgap winding electromagnetic force of the generator during operation were clarified, based on a three-dimensional magnetic field analysis. The structure of this airgap winding stator is sufficiently durable for use in the 50 MVA superconducting generator.
