A collector for an electric motor consisting of flat copper lamella elements which are distributed on the periphery and are anchored in an insulating carrier made from a plastic pressed material with internal web-type elements exhibiting undercuts. At least one armouring ring with a clamping ring made of an electrically conducting material are included in the carrier which engages with the inner web-type elements on extensions in the region of the undercuts and which is made of an insulating material at least on the inner side thereof facing the extensions. In order to simplify production and obtain improved quality, a single piece structure is provided for the entire armouring ring, exhibiting high mechanical and thermal resilience, whereupon the clamping ring part is formed by a winding of filaments surrounding the supporting ring part.
