Abstract
Flux analysis by the three-dimensional finite element method is applied to the end region design of large-capacity turbine-generators. Analysis has been done considering three-dimensional electric currents of end region windings and anisotropies of iron cores provided at the end regions. It becomes possible to quantitatively evaluate the effects of flux shunts which has been impossible to do with two-dimensional analysis, and to control leakage flux of end regions. Significant informations on the influence of the relative lengths of stator and rotor cores on end region flux and the optimum stator core end design of large-capacity turbine-generators with lower short-circuit are described.Keywords
