The invention relates to a primary-sided arrangement (1) of primary winding structures (W1, W2, W3) of a system for inductive power transfer, wherein the primary-sided arrangement (1) comprises at least three phase lines and at least one winding structure (W1, W2, W3) per phase line, wherein each winding structure (W1, W2, W3) comprises at least one subwinding structure (SW1_1, . . . , SW3_3), wherein the winding structures (W1, W2, W3) extend along a longitudinal axis (x) of the primary-sided arrangement (1), wherein a pitch (P12_1, . . . , P32_3) between corresponding subwinding structures (SW1_1, . . . , SW3_3) of the winding structures (W1, W2, W3) varies along the longitudinal axis (x) and/or a length (L_SW1_1, . . . , LSW1_3) of the subwinding structures (SW1_1, . . . , SW3_3) of the winding structures (W1, W2, W3) varies along the longitudinal axis (x). The invention further relates to a system for inductive power transfer, to a method of manufacturing a primary-sided arrangement (1) and to a method for inductively supplying power to a vehicle.
