Refurbishment method for the coil end of the rotor of an electric generator

摘要

The method involves removing the old coils and replacing the old coils by new coils such that one-piece half-windings of a section parallel to a rotor axis (2) and of two arc-shaped sections in the area of two coil ends (5) are used. The arc-shaped sections of the coils are reduced with respect to their profile width by material degradation with a part of the windings or with all windings.
