A dynamoelectric machine having a casing structure which includes a thin cylindrical member, circumferentially separated axial gussets attached to the cyclindrical member's interior, at least two axial rows of arcuate structural segments connected between the axial gussets, a cylindrical stator core, and a stator winding distributed on the stator core and having phase terminals. Conductor rings and ring extensions protruding therefrom are supported within the casing structure at one axial end thereof by conductor ring clamp systems and ring extension clamp structures respectively. Circumferential positions of the ring extensions correspond to the circumferential positions of the phase terminals. Phase leads which electrically connect the phase terminals and the ring extensions have standard lengths. the number of phase lead standard lengths equal the number of different radial distances the phase terminals are displaced from the stator core's axis. Attaching the conductor ring clamping systems to the arcuate structural segments permits clamping system disposition at the circumferential positions corresponding to the ring extensions' positions. The ring extension clamp structures connect to the conductor ring clamp systems and provide optimum rigidity to the ring extensions. The conductor ring clamp systems each include two blocks which each have indentations in one edge. The indentations on one block are juxtaposable with the indentations on the other block so as to cooperatively provide openings for the reception and retention of the conductor rings. The ring extension clamp structures are similarly configured, but usually have only one indentation in each block for receiving and retaining the ring extension.
