• wherein the x-winding section and the y-winding section are arranged parallel to the positioning plane and take up, at least partially, the same xy region in the xy coordinate system, such that the x-travelling field and the y-travelling field overlap in this xy region, and
• wherein the x-winding section comprises a plurality of x-wire sections running in the direction of the y-axis and arranged one next to the other on an x-plane parallel to the positioning plane, the y-winding section comprises a plurality of y-wire sections running in the direction of the x-axis and arranged one next to the other on a y-plane parallel to the positioning plane, and the x-wire sections and the y-wire sections are arranged one over the other in the direction perpendicular to the positioning plane, such that, in the top view onto the xy coordinate system, a plurality of crossing points results between the x-wire sections and the y-wire sections, and
• wherein the carriage support is provided with a control circuit, which is formed to supply several currents, which are phase-shifted with respect to one another, to at least one x-winding section and at least one y-winding section for providing the respective travelling field.
