ELECTRICAL MACHINE STATOR Russian patent published in 2005 - IPC

FIELD: electromechanical engineering; large electrical machines such as turbogenerators with directly cooled stator core.

SUBSTANCE: proposed electrical-machine stator has laminated core 1 clamped by means of nonmagnetic studs 2 installed in a spaced relation in axial holes 6 of core yoke and insulated from core 1. Nonmagnetic studs 2 are installed on flexible insulating supports 8 disposed in annular slots 9 of core. Diameter of supports 8 is greater than that of axial hole of core yoke receiving the stud; these supports are spaced apart through stud length to ensure tuning inherent stud vibration frequency away from core vibration frequency. Tangentially positioned side slots are made at location points of insulating supports 8.

EFFECT: enhanced operating reliability of electrical machine.
