Abstract: The invention relates to an electromagnet coil assembly in particular an electromagnet coil assembly at least comprising a core; a winding constituting the coil being wound in a plurality of turns around said core; and multiple power taps for electrically connecting the winding to an external power circuit. Most electromagnetic coils implementing HTS materials are wound for academic purposes, which are generally hand-wound. Any coil needs power leads or power taps of some sort. However, in academics applications, coils are usually “one-offs” and not much time is invested in the manufacturability on a large scale and quantity basis. It is thus an object of the present invention to provide an electromagnet coil assembly implementing HTS materials, which coil assembly can be mass-manufactured in a reliable, robust and cost-effective manner.

Abstract: The invention relates to an actuator device for use in a positioning system, wherein the actuator device is linearly movable within a plane with respect to a supporting structure of the positioning system as well as such a positioning system implementing such an actuator device. In an example of the actuator device according to the invention, it comprises a carrier having a longitudinal and a transversal dimension; and multiple groups of coil assemblies mounted in the carrier, each group of coil assemblies being structured to orientate the carrier in at least one degree of freedom. The single design actuator device according to the invention has limited constructional dimensions and allows high accuracy as to motion and position in multiple degrees of freedom.
