A generator stator end winding coil support assembly is presented. The assembly includes a bracket rigidly secured to a core flange plate and a brace clamped between a backup plate and the bracket by studs. The brace connects to an inner support ring. An elastic layer is disposed around the brace. Sleeves are disposed in apertures of the brace and enclose the studs. The sleeves set up a gap at interfaces between the brace and the bracket and between the brace and the backup plate that defines a compression of the elastic layer. The compression enables the brace to be movable relative to the bracket rigidly secured to the core flange plate for flexibly supporting the end winding coils. Flexibility and stiffness of the support is controllable by adjusting clamping force of the studs and selection of the elastic layer based on load conditions during operation.

Generator stator end winding coil support assembly

A method of removing a stator coil () from a stator core () of an electrical generator, including vibrating an unbonded portion () of the coil () until a resin bond material () between a bonded portion of the coil () and a surface () of the core () fails due to high cycle fatigue to free the coil () from the core ().
