<p>A commutator for an electric machine comprises a support member ( 1 ) made from an insulating molding compound, a plurality of metal conductor segments ( 3 ) disposed thereon in evenly spaced manner around the commutator axis ( 2 ), with terminal elements disposed thereon for a rotor winding, and an interference-suppression device ( 9, 9 '), to which the conductor segments ( 3 ) are connected in electrically conductive manner and which comprises a number of individual interference-suppression elements ( 10 ) corresponding to the number of conductor segments ( 3 ), wherein the conductor segments ( 3 ) are provided with contact tabs ( 18 ), which are respectively connected, at a distance from their root points ( 19 ), via associated contact points ( 23 ), to the adjoining contact poles ( 24 ) of two neighboring interference-suppression elements ( 10 ). These contact tabs ( 18 ) are designed to be radially resilient and, in the region between their root point ( 19 ) and their contact point ( 23 ), are separated from the adjacent rigid components of the commutator in such a way that, in this region, the position of the contact tabs ( 18 ) relative to that of these respective rigid adjacent components of the commutator can vary as a function of thermal expansion.</p> |
