Abstract

A slip ring unit for an electrically excited rotor of a rotary dynamo-electric machine includes an electrical terminal which protrudes axially from an end face of the slip ring unit and having a contact point and a circumferential slip contact surface electrically connected to the electrical terminal. Disposed adjacent to the slip contact surface is an insulation element, with end plates axially retaining the circumferential slip contact surface and the insulation element. An electrically insulated support element is arranged on an end face of the slip ring unit and has a cross section which substantially matches a cross section of the slip ring unit. The support element axially surrounds the electrical terminal and radially supports the electrical terminal.
