A primary-sided arrangement of primary winding structures of a system, wherein the primary-sided arrangement includes at least three phase lines and at least one winding structure per phase line, wherein each winding structure includes at least one subwinding structure, wherein the winding structures extend along a longitudinal axis of the primary-sided arrangement, wherein a pitch between corresponding subwinding structures of a first winding structure and a second winding structure is chosen from an interval of a length of one subwinding structure, and wherein a pitch between corresponding subwinding structures of the first winding structure and the third winding structure is smaller than the pitch between corresponding first and second subwinding structures.
