Axi-periodic analysis for end region of large turbin generator is studied and verified by 3D-FEA in this paper. Verification is done by comparing three components of flux densities from axi-periodic analysis and 3D FEA in static field, and the comparison shows some difference, and the cause of those differences are errors would be acceptable for initial design of large turbin generator, Then, axi-periodic analysis is extended to time harmonic field for its application. From the time harmonic field analysis, the effect of flux shield and addy current loss in the flux shield for power angles are presented.
