ABSTRACT:
A resilient stator coil support bracket is provided particularly useful for large hydrogen innercooled turbine generators to give the end winding support assembly greater axial flexibility without substantially increasing the radial flexibility of the assembly. The support bracket includes an element secured to the core as well as an element secured to the brace that is radially outside each coil end turn with a sheet of resilient material therebetween, or there are two elements of the brace secured to the core with an intermediate element secured to the brace and the mating surfaces of all adjacent elements are spaced by sheets of resilient material, such as of an elastomer, that flexes in shear and compression modes. The bracket is tunable in the sense that the selection of the thickness and composition of the resilient material permits adjusting the natural frequency of the assembly to avoid resonance with the excitation frequency which such gas-cooled generators are sometimes susceptible. Also, the resilient bracket can be easily installed in the field to replace rigid brackets on machines in which the vibration problem has appeared.
