The factors such as rotor motion and non-linearity of the time-varying electromagnetic field, the stator slots skew, the anisotropic heat conduction of the rotor core lamination and different heat dissipation conditions on the windward and lee side of the poles are considered. Furthermore, according to the different operating conditions, different rotor structures and materials, compositive calculations about the losses and temperatures of the damper bars of a 36 MW generator are carried out, and the data are compared with the test. The results show that the computation precision is satisfied and the generator design is reasonable.}, type={Artykuły / Articles}, title={Calculation and analysis of the loss and heat on damper bars in large tubular hydro-generator}, URL={http://journals.pan.pl/Content/84744/PDF/04_paper.pdf}, doi={10.2478/aee-2013-0004}, keywords={loss and heat, damper bars, tubular hydro-generator, electromagnetic field and temperature field}, }
