Slip ring unit for a rotor of an electrically excited rotary dynamo-electric machine
First Claim
1. A slip ring unit for an electrically excited rotor of a rotary dynamo-electric machine, said slip ring unit comprising:
- an electrical terminal protruding axially from an end face of the slip ring unit and having a contact point;
a circumferential slip contact surface electrically connected to the electrical terminal;
an insulation element disposed adjacent to the slip contact surface;
end plates axially retaining the circumferential slip contact surface and the insulation element;
an electrically insulated support element arranged on an end face of the slip ring unit and having a cross section which substantially matches a cross section of the slip ring unit, said support element disposed in axial surrounding relation to the electrical terminal and radially supporting the electrical terminal; and
an insulation surrounding the electrical terminal such that the contact point remains exposed.

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.
