Abstract
System for contactless energy transmission includes a primary side winding and a secondary side winding that is rotatable relative to the primary side winding, a coil core being provided on the primary side winding, whose sectional view in at least one sectional plane containing the axis of rotation is formed as a U shape or C shape around the winding region of the primary side winding.
Claims19
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.
