1. A primary-sided arrangement of primary winding structures of a system for inductive power transfer, comprising:
at least three phase lines; and
at least one primary winding structure per phase line;
wherein each primary winding structure comprises at least one subwinding structure, wherein the at least one subwinding structure comprises a loop or a coil, and wherein the at least one subwinding structure of each primary winding comprises a flat winding structure arranged in a two-dimensional plane;
wherein the primary winding structures extend along a longitudinal axis of the primary-sided arrangement, wherein a first pitch between corresponding subwinding structures of a first primary winding structure and a second primary winding structure is chosen from an interval of a length of the subwinding structure and wherein the first pitch is a distance between geometric centres of the corresponding subwinding structures of the first and the second primary winding structures along the longitudinal axis;
wherein a second pitch between corresponding subwinding structures of the first primary winding structure and a third primary winding structure is smaller than the first pitch between the corresponding subwinding structures of the first primary winding structure and the second primary winding structure and wherein the second pitch is a distance between geometric centres of the corresponding subwinding structures of the first and the third primary winding structures along the longitudinal axis; and
wherein the at least one subwinding structure of the first primary winding structure is arranged in a first plane, the at least one subwinding structure of the second primary winding structure is arranged in a second plane, and the at least one subwinding structure of the third primary winding structure is arranged in a third plane, wherein the first plane, the second plane, and the third plane are arranged at different vertical positions along a vertical axis, and wherein the vertical axis is oriented parallel to an axis of symmetry of the at least one subwinding structure of the first primary winding structure.
