    摘要: A method of making contact wires (200, 201, 202, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 440) for sliprings (160) comprising the steps of:

    coating and/or plating a wire with a first metal of the group of nickel, chrome or a combination thereof;

    coating and/or plating the wire with a second metal of the group of gold, silver, or a combination thereof;

    delivering laser radiation (611, 612) and generating an interference pattern of the laser radiation to the surface of the wire;

    heating the surface selectively as defined by the interference pattern, modifying of the crystal structure and/or providing protrusions and/or recesses d ue to melting and/or evaporation of the surface material.

    摘要: The invention relates to a spring contact for a sliding contact having a terminal region (24) and at least one contact region comprising an elongated spring element and a precious metal, wherein the spring contact comprises a conductive spring support (1, 11, 21, 31) and at least one contact piece (2, 12, 22, 32), wherein the spring support has a substantially symmetrical rigidity in some regions in a plane perpendicular to the elongated extent of the spring support and is made from a conductive material, substantially free of precious metal and wherein the at least one contact piece is conductively connected to the spring support, and comprises at least one surface to form the sliding contact and the material of the surface of the contact piece comprises a precious metal or a precious metal alloy. The invention also relates to a slip ring transmitter comprising such a spring contact, wherein the surface of the contact piece(s) is/are conductively connected to the slip rings, and also relates to a motor and a dynamo having such a slip ring transmitter.
