Patent ID: 7462972

Claim:
A commutator for an electric machine, comprising a support member ( 1 , 1 ″) made from insulating molding compound, a plurality of metal conductor segments ( 3 , 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 ′, 9 ″), to which the conductor segments ( 3 , 3 ″) are connected in electrically conductive manner, wherein the interference-suppression device ( 9 , 9 ′, 9 ″) comprises a number, corresponding to the number of conductor segments ( 3 , 3 ″), of individual interference- suppression elements ( 10 , 10 ′, 10 ″) disposed around the commutator axis ( 2 ), and an equally large number of contact bridges ( 11 , 11 ′, 11 ″), each of which is connected to an associated conductor segment in electrically conductive manner and connects two mutually adjacent interference-suppression elements ( 10 , 10 ′, 10 ″) to one another and to the associated conductor segment in electrically conductive manner, characterized in that each contact bridge ( 11 , 11 ′, 11 ″) is provided with two inwardly directed legs ( 20 , 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 , 21 ′), which is connected to the associated conductor segment in electrically conductive manner, the contact bridges ( 11 , 11 ′, 11 ″) being soldered or adhesively bonded in the region of their leg ( 20 , 20 ′) to the associated interference-suppression elements ( 10 , 10 ′, 10 ″) and in the region of their foot portions ( 21 , 21 ′, 21 ″) to the associated conductor segments ( 3 , 3 ″).
