A commutator for an electric machine comprises a support member made from insulating molding compound, a plurality of metal conductor segments ( 3 ), 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. This interference-suppression device comprises a number, corresponding to the number of conductor segments ( 3 ), of individual interference-suppression elements ( 10 ') disposed around the commutator axis, and an equally large number of contact bridges ( 11 '), each of which connects two mutually adjacent interference-suppression elements ( 10 ') to one another in electrically conductive manner, the contact bridges ( 11 ') each being provided with two inwardly directed legs ( 20 '), which are flexible relative to one another in circumferential direction and are connected to the two associated interference-suppression elements in electrically conductive manner, and with one outwardly directed foot portion ( 21 '), which is connected to the associated conductor segment in electrically conductive manner.
