MOUNTING ARRANGEMENT FOR STATOR END WINDINGS OF TURBINE GENERATOR Russian patent published in 2015 - IPC H02K3/50 

FIELD: electricity.

SUBSTANCE: stator comprises a core with laid rods of winding. End windings are rigidly fixed between conical surfaces of inner and outer insulating rings. At cylindrical surface of outer ring there is a flat spring ring, through which the outer ring is fixed rigidly to the core clamping plate. The spring ring is made of metal non-magnet material. Between the spring ring and clamping plate there is a remote element at the distance defined by the remote element in axial direction. At cylindrical surface of the outer ring there are brackets with connected connecting buses, which are fixed rigidly to output rods in the area of end winding heads.

EFFECT: excluding formation of fatigue cracks, reduced level of bending deformation and strain concentration in connections and frame insulation of the stator wining rods and connecting buses.
