It was of great importance for generator op-eration security to calculate the temperature distribution of various kinds of main components during the design stage of the generator. The sinusoidal traveling wave FEM theory and finite element analysis method were applied to calculate and analyze the end electromagnetic field of the stator as well as the coupled temperature field. The calculation re-sults showed that the generator end structure as well as air duct design was reasonable and reliable, with a wide margin of the temperature rise of this end structure.
