Summary:A collector for electric machines, including a rotationally symmetrical sintered ceramic body and a plurality of radially disposed metallic segments which are separated from each other by one interspace each and which are bonded to the ceramic body via a eutectic intermediate layer. The segments are bonded to the ceramic body in accordance with the eutectic method by being surface-oxidized on their inside narrow side and radially pressed against the ceramic body with the totality being brought to the melting temperature corresponding to the metal/metal-oxide eutectic and subsequently being cooled down again. A preferred embodiment includes: copper segments on an Al2O3 ceramic body.
