Abstract
A commutator for an electric machine comprises a support member () made from an insulating molding compound, a plurality of metal conductor segments () disposed thereon in evenly spaced manner around the commutator axis (), with terminal elements disposed thereon for a rotor winding, and an interference-suppression device ('), to which the conductor segments () are connected in electrically conductive manner and which comprises a number of individual interference-suppression elements () corresponding to the number of conductor segments (), wherein the conductor segments () are provided with contact tabs (), which are respectively connected, at a distance from their root points (), via associated contact points (), to the adjoining contact poles () of two neighboring interference-suppression elements (). These contact tabs () are designed to be radially resilient and, in the region between their root point () and their contact point (), are separated from the adjacent rigid components of the commutator in such a way that, in this region, the position of the contact tabs () relative to that of these respective rigid adjacent components of the commutator can vary as a function of thermal expansion.
