Publication number: 20240146163Abstract: In a method for producing a short-circuit rotor of an asynchronous machine, a laminated core is formed with substantially axial slots and with an axial skew over an axial length of the laminated core, which axial skew is 0.3 to 3 times a slot pitch of the rotor. Conductor bars made of a first conductive material are inserted into the slots such that the conductor bars protrude out of end faces of the laminated core in a skewed manner out of the laminated core to define overhangs. At least the overhangs are coated with a galvanic layer of aluminum, tin or a solderable alloy to provide a lubricating layer. Individual laminations of a second conductive material are axially pressed onto the conductor bars such that the individual laminations short-circuit the conductor bars and form a short-circuit ring, which is composed of multiple individual laminations.Type: ApplicationFiled: March 1, 2022Publication date: May 2, 2024Applicant: Siemens AktiengesellschaftInventors: KLAUS BÜTTNER, KLAUS KIRCHNER, MATTHIAS WARMUTH

Patent number: 10199811Abstract: A plastic corrugated tube having corrugations distributed over its length and a longitudinal slit running along a lateral longitudinal line is provided. The corrugated tube can be converted into an open position by opening the longitudinal slit and into a closed position in which edge regions of the corrugated tube overlap, wherein the corrugated tube is elastically prestressed toward its closed position. The corrugations on the edge region of the corrugated tube, which in the closed position lies radially below the other edge region of the corrugated tube, are offset radially inwards within a predefined circumferential region with respect to the corrugations outside this circumferential region and are designed such that, in the closed position, they are in engagement with the radial underside of the corrugations of the other edge region, which corrugations engage over them such that they are mutually displaceable in the circumferential direction.Type: GrantFiled: May 19, 2015Date of Patent: February 5, 2019Inventors: Van Ngoc Chu, Matthias Buettner

Patent number: 10035371Abstract: A device for connecting two objects, especially for holding a writing instrument on a notebook or the like, with a clamping body having clamping arms extending across a narrow side, for example, of the notebook, which clamping body grips one of the objects in a pliers-like fashion with its clamping arms and forms a holder for holding the other object, e.g., the writing instrument, parallel to the longitudinal direction of the narrow side. Mechanisms are provided to spread open the clamping arms.Type: GrantFiled: December 29, 2014Date of Patent: July 31, 2018Assignee: X17 GMBHInventor: Matthias Büttner

Publication number: 20170141553Abstract: A plastic corrugated tube for surrounding pipes, having corrugations distributed over its length and a longitudinal slit running along a lateral longitudinal line is provided. The corrugated tube can be converted into an open position by opening the longitudinal slit and into a closed position in which edge regions of the corrugated tube overlap, wherein the corrugated tube is elastically prestressed toward its dosed position. The corrugations on the edge region of the corrugated tube, which in the closed position lies radially below the other edge region of the corrugated tube, are offset radially inwards within a predefined circumferential region with respect to the corrugations outside this circumferential region and are designed such that, in the closed position, they are in engagement with the radial underside of the corrugations of the other edge region, which corrugations engage over them such that they are mutually displaceable in the circumferential direction.Type: ApplicationFiled: May 19, 2015Publication date: May 18, 2017Inventors: Van Ngoc Chu, Matthias Buettner
