Taking into account the anisotropy and saturation stator core with help a quasi-three dimensional mathematical model for a number of variants the design of a stator core end zone of powerful turbogenerator on the conditions of reactive power consumption the distribution of magnetic induction and temperature in elements is obtained. By the criterion of decreasing the maximum and average temperature in the construction elements a comparative analysis of efficiency for these variants is made. References 11, figures 11, table 1.
Key words: turbogenerator, end zone, stator core extreme packet, temperature.
