Abstract :
Comparisons have been made between measurements and calculations of magnetic-flux in turbogenerator end-regions. The results of measurements on two 500 MW generators are presented. Two methods of calculation are reviewed. A method is given for relating the results derived from measurements and calculations to the load conditions. It is concluded that the use of a nonmagnetic rotor end-bell on these large generators willreduce eddy-current heat of the core-end.
