Abstract:
1. A device for a contactless transfer of energy and data, comprising: a primary winding arrangement arranged on a first support, wherein the primary winding arrangement has at least one energy winding for an inductive transfer of electrical energy, and wherein the primary winding arrangement has at least one data winding for an inductive transfer of data; a secondary winding arrangement arranged on a second support, wherein the first support and the second support are rotatable in relation to one another, wherein the secondary winding arrangement has at least one energy winding for the inductive transfer of electrical energy, and wherein the secondary winding arrangement has at least one data winding for the inductive transfer of data; and at least one data turn of the data winding to enclose at least one energy turn of the energy winding such that a first part of the data turn is wound in a winding direction of the energy winding and a second part of the data turn is wound counter to the winding direction of the energy winding, wherein the data winding is arranged relative to the energy winding such that magnetic field strength components generated by the energy winding compensate each other within a surface area which is enclosed by the data turn.
