The invention relates to a rotary transmitter and an electric motor for the inductive transfer of energy from a primary coil to a secondary coil, which is rotationally fixed to a rotor shaft that is rotatably mounted relative to the primary coil. The rotary transmitter is characterized in that the secondary coil has a coil core and a secondary winding, in particular an annular winding, which are accommodated in a receiving part, in particular wherein the receiving part is rotationally fixed to the rotor shaft, wherein a cover part is connected to the receiving part, wherein the secondary winding is arranged between the cover part and the receiving part, wherein the coil core is arranged between the cover part and the receiving part, wherein the coil core has a yoke disk having at least two limbs connected via the yoke disc, in particular wherein the secondary winding is arranged between the limbs, wherein the cover part has axially continuous cutouts spaced apart from one another, in particular regularly, in the circumferential direction, wherein the radial spacing region of the respective recess covers, in particular completely covers, the radial spacing region of the coil core or at least of a first limb of the coil core, wherein the axial region covered by the cover part overlaps, in particular truly overlaps, in particular partly covers, the axial region covered by the coil core, in particular wherein the coil core projects axially into the respective cutout, in particular wherein the cutouts are each shaped as a circular ring section. |
