Abstract
A coil end-turn support structure for large dynamoelectric machines including a plurality of bracket assemblies which support the coil end-turn windings in a fixed position with respect to the main body of the machine in all directions except the axial direction. Ball bearings are captivated in slots in the bracket assemblies so as to provide free and smooth movement of the end-turns in the axial directions while providing rigid support of the end-turns in all other directions.
