Abstract: 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.
