Publication number: 20200169158Abstract: The invention relates to a synchronously excited rotary machine with a superconductive rotor comprising a plurality of projecting first pole units of a magnetic material and a plurality of second pole units having superconductive coils wrapped around a core element of a magnetic material. Each second pole unit is positioned between two adjacent first pole units. The second pole units are spaced apart from aback iron and the first pole units via a plurality of thermally insulating support elements, wherein this spacing is evacuated so that it acts as magnetic air gap. An enclosed housing is provided on the back iron in which the first and second pole units are arranged, where-in the superconductive coils of the second pole units are in fluid communication with a cooling system. The first pole units and back iron are operated at an ambient temperature while the second pole units are operated at a cryogenic operating temperature.Type: ApplicationFiled: December 1, 2016Publication date: May 28, 2020Inventors: Carsten Bührer, Jürgen Kellers, Jan Wiezoreck

Publication number: 20120129700Abstract: A linear machine comprises a primary part and a secondary part. The primary part forms a receptacle around an axis and has a plurality of annular primary coils, which are arranged concentrically with respect to the axis, can have alternating current applied to them, and are separated by intermediate elements, in order to produce a magnetic field in the receptacle. The secondary part, which can be moved relative to the primary part by the magnetic field in the receptacle along the axis, is provided with secondary coils having superconductor windings. In order to produce a linear motor which allows high force densities, the intermediate elements are produced from non-magnetizable material and the primary coils and the secondary coils are arranged with an air-gap winding, wherein the secondary coils are manufactured from a high-temperature superconductor and direct current can be applied or is applied to them. Force densities of more than 18 N/cm2 can be achieved in the receptacle by the linear motors.Type: ApplicationFiled: March 25, 2008Publication date: May 24, 2012Inventors: Jan Wiezoreck, Ingolf Hahn, Carsten Bührer, Jakob Fallkowski
