Abstract
In order to estimate the losses and temperature rise at the end of electric al machines, it is important to clarify electromagnetic behavior in the cor e end region. In this paper, the method of evaluating the leakage flux of t he stator end region of large turbogenerators, combining three-dimensional magnetic field analysis and phasor diagram analysis of the end leakage flux is described. Moreover, the result of applying this method to a 60 Hz-1000 MW turbogenerator is also described.
