Abstract
An inductive transformer for transmitting measurement data and/or electrical energy between two components ( ) moving relative to one another includes one primary and one secondary transformer part ( ), in which a gap is formed between the moving components ( ). A slide ring ( ), which is made of a plastic with embedded ferromagnetic metal parts is disposed in the gap. The metal parts are distributed nonhomogeneously in the plastic, such that their proportion, on the end with which it is solidly disposed on one of the components ( ), is high and becomes relatively slight toward the end with which it rubs against the respective other component ( ).
