Publication number: 20230274852Abstract: The invention relates generally to the field of insulating electrical conductors against partial discharge in the medium- and high-voltage ranges. In particular, the invention relates to an insulating system for an electric machine, in particular a rotating electric machine such as an electric motor and/or a generator. The invention provides for the first time a substitute for the conventionally used mica as a barrier material in an insulating system, such as the main insulation of rotating electric machines such as motors and/or generators. The substitute is based on a polyether-imide/siloxane copolymer, which can be processed two-dimensionally, for example by surface extrusion. In this way, sheets are produced and, after being processed in sheet form or as a laminate, can be used as planar insulating materials, or cut as strips, in insulating systems.Type: ApplicationFiled: July 7, 2021Publication date: August 31, 2023Inventors: Florian Schemmel, Steffen Lang, Manfred Ochsenkühn, Niels Müller, Marek Maleika

Publication number: 20200039148Abstract: Conveyed goods of grains are fed from a pressure vessel into a conveyor line at a feed point for conveyance to a discharge point for supply to an extrusion head. The goods are plasticized in the extrusion head and extruded in a punctiform manner via a nozzle of the extrusion head. The extrusion head is moved dynamically by a manipulator during extrusion of the plasticized goods. Conveyor gas is force into the conveyor line by a gas compressor and allowed to escape the conveyor line at a separation point in a region of the discharge point. A gas positive pressure is temporarily applied by the gas compressor to the pressure vessel as the goods are fed from the pressure vessel into the conveyor line while bypassing the conveyor line via a first valve and closing a second valve in the conveyor line between the feed point and the gas compressor.Type: ApplicationFiled: February 2, 2018Publication date: February 6, 2020Applicant: Siemens AktiengesellschaftInventors: JENS JÄHNICKE, MANFRED OCHSENKÜHN, SONJA WOLFRUM

Patent number: 10153670Abstract: The invention relates to a rotor (10) for a reluctance machine (E), wherein the rotor (10) has a laminate stack (14) with layers (16), each of the layers having a plurality of flux-conducting portions (24) which are formed in each case by a magnetically conductive rotor lamination (18) and extend between two adjacent d-axes and transversely to a respective q-axis (30), wherein the flux-conducting portions (24) are separated from each other by in each case a flux barrier (22) which is filled with a casting compound. The aim of the invention is to additionally provide a permanent magnetic excitation in the rotor (10) without degrading the reluctance of the rotor. To this end, the invention provides that the casting compound comprises permanently magnetic particles (36) in one or more or each of the flux barriers (22).Type: GrantFiled: June 7, 2016Date of Patent: December 11, 2018Assignee: Siemens AktiengesellschaftInventors: Klaus Büttner, Marco Cerny, Robert Greiner, Manfred Ochsenkühn, Matthias Warmuth

Patent number: 6921445Abstract: A method involves sheathing a superconductor with a thermoplastic insulation material on all sides. The conductor exits a guide channel that extends in the propulsion direction. A melt hose is extruded from the molten insulation material in the propulsion direction and through a nozzle that has an outlet which embraces the conductor, whereby a distance is kept on all sides. The melt hose is stretched via the propulsion of the conductor. The hose is drawn to the surface of the conductor and is compacted by cooling. The method can especially be used for sheathing band-shaped high-Tc-superconductors. Materials having processing temperatures between 200° C. and 450° C., are selected as thermoplastic insulation materials.Type: GrantFiled: January 30, 2001Date of Patent: July 26, 2005Assignee: Siemens AktiengesellschaftInventors: Cord Albrecht, Robert Greiner, Peter Kummeth, Peter Massek, Manfred Ochsenkühn
