Optimal schemes for installing vibration acceleration sensors, a device for monitoring the stator core tightening forces, and diagnostic procedures have been developed. To confirm the theoretical positions, experiments were conducted on a physical model of the final zone of the stator core of a turbogenerator. The influence of the development of pressing defects of the tooth zone of the core on the harmonics of vibrations of the fundamental frequency of electromagnetic forces is established. Reference 12, figures 5.
Key words: turbogenerator, modeling, lined magnetic core, stator core, tooth zone, pressure fingers, mechanical stresses, forces, linear elongation.
