Abstract
The invention relates to a rotary transmitter for example for use in machine tools with adjusting tools. The rotary transmitter comprises a stator part () and a rotor part (), each having a respective stator core part () and a rotor core part (), which are separated from one another at mutually facing ends via an air gap, and each having at least one respective power winding (), which is wound on the stator core part and the rotor core part, in order to transmit power using the transformer principle, and having respective stator and rotor coupling turns (″), which are associated with one another in pairs, for inductive data transmission. One aim of the invention is to transmit data without interference. A further aim is a low maintenance requirement. In order to achieve this, the invention primarily proposes that the coupling turns (″) are separated from the area of the power winding (), and are shielded from them, by parts of the respective core parts (), and are arranged in the associated stator part and rotor part () in each case forming a three-dimensioned curved loop.
