The invention relates to a rotational transmitter for example for using in machine tools with adjustment tools. Said rotational transmitter comprises a stator part (18) and a rotor part (26), each comprising a core part (72, 74) on the stator side and on the rotor side, said core parts being separated from each other by an air gap, on one of the facing ends. The stator part and the rotor part also comprise at least one energy winding (76, 78) which is wound on the stator-side and rotor-side core parts and used for the transmission of energy according to the transformer principle, and stator-side and rotor-side coupling windings (80', 80'', 82', 82'') which are associated with each other in pairs for the inductive data transmission. The aim of the invention is to enable interference-free data transmission and to reduce the maintenance cost. To this end, the coupling windings (80', 80'', 82', 82'') are separated from the region of the energy windings (76, 78) by parts of each core part (72, 74), are shielded therefrom, and arranged in the associated stator and rotor part (18, 26), respectively forming a spatially curved loop. |
