Abstract
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 an axis of the primary-sided arrangement, wherein a pitch between corresponding subwinding structures of a first and second winding structures is chosen from an interval of a length of one subwinding structure, wherein a pitch between corresponding subwinding structures of the first winding structure and the third winding structure is smaller than the pitch between corresponding subwinding structures of the first and second winding structures.
