Abstract
Based on the calculated model, was made a magnetic field analysis of the turbo generator in its end zone. The average and maximum values of the magnetic induction in the stator core packages and end zone elements, the distribution of induction along axial and radial lines the transverse and longitudinal sections of the generator are considered. The presented method can be considered quasi-three-dimensional, since it takes into account the interrelated magnetic fields of two sections the turbo generator. References 13, figures 11.
