Abstract
The flux distribution in the end region of turbogenerators close to the stator surface is analysed with particular reference to the unwanted axial component of flux. It is shown that axial flux levels at the stator surface can be considerably reduced by making the rotor shorter than the stator and by stepping or rounding the stator ends. The influence of conducting screens is studied, and it is shown that these produce flux concentrations at their edges.Keywords
