A model is developed for calculating the mechanical characteristics in pressure fingers and plates for defects in pressing the stator core of a turbogenerator in the tooth zone, incl. when the finger is bent. The model makes it possible to determine the frequency of oscillation of the system at the initial moment of the sudden appearance of defects, as well as the characteristics in the steady-state operating mode. Test calculations of mechanical characteristics in the fingers and in the slabs at the area of their contact when the finger is bent. References 10, figures 6, table 1.
Key words: turbogenerator, modeling, laminated magnetic circuit, stator core, tooth zone, pressure fingers, mechanical stresses, forces, linear elongation.
