Abstract
In large electric machines, the electrical connection between the exciter supply lead (5, 6), which extends axially in the center of the rotor, and the exciter winding conductors in the winding overhang of the rotor is highly stressed electrically and mechanically. If the terminal stud (1) is slotted in the shank (2) in the longitudinal direction of the stud, there being provided at least three slots (13) which extend radially up to the longitudinal axis of the stud, the stud becomes more elastic transversely to the longitudinal direction, and it can be purposively cooled.
