1. A system for contactless energy transmission, comprising:
- a primary side winding suppliable with a voltage of medium frequency, a coil core provided on the primary side winding, the coil core, in a sectional view in at least one sectional plane, includes an axis of rotation and is formed by a plurality of at least one of (a) U-shaped and (b) C shaped parts around the winding region of the primary side winding, wherein each part is separated by an air gap, wherein the plurality of at least one of (a) U-shaped and (b) C-shaped parts are situated on a circumference of the winding and having shanks oriented in a direction that is oriented parallel to the axis of rotation;
a secondary side winding that is rotatable relative to the primary side winding; and
a parallel-resonant circuit provided on the secondary side winding.
