Abstract
A device for contactless transfer of energy and data. One embodiment includes a primary coil assembly on a first support and a secondary coil assembly on a second support, the supports rotatable in relation to one another, the primary and secondary coil assemblies having an energy coil for inductive transfer of electric energy. To minimize interference in data transfer, the primary and secondary coil assemblies may include at least one data coil for inductive data transfer wherein at least one winding of the data coil surrounds at least one winding of the energy coil so that a first section of the data winding is wound in the wound direction of the energy coil and a second section of the data winding is wound in a direction opposite the wound direction of the energy coil.
