Abstract: A rotor of a dynamo-electric machine having the conductors forming an end-winding supported by an annular support arrangement interposed between an overhang region of the rotor body and the conductors forming the end winding. The annular support arrangement may comprise a single annular member or a plurality of separate members secured around the overhang region of the rotor body. The annular support arrangement may be formed from a non-magnetic metal of low density, for example, an aluminium alloy, or may be formed from a suitable insulating material, for example, a fibre reinforced composite material.

Abstract: A plurality of conductors are surrounded by a continuous, flexible belt which is doubled over to provide loops at each end thereof. Non-metallic rods are disposed through the loops for providing surfaces to which a non-metallic buckle or strap is connected for securing the belt. The belt consists of a plurality of glass fiber cords which are surrounded by a cured elastomeric material. The cords are formed from glass fiber strands which are twisted sufficiently to provide the desired amount of belt strength and flexibility.
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.
Abstract: Apparatus for securing the end winding conductors of turbine generators. Support rings extend around the end winding conductors and are braced against the conductors by resin filled hoses located therebetween. The hoses extend around the circumference of the support rings and are pressure filled with a curable resin to produce a force between the conductors and the support rings.
