The results of physical modeling of surface whirling currents in the turbogenerator stator core end segments with different quantity of tooth are presented. It is shown that from point of view of electromagnetic losses there arent practical use in replacement of six-tooth segments with three-tooth segments. References 2, figures 3.
Key words: turbogenerator, core segments, electromagnetic losses, whirling currents.
