Patent number: 11811280Abstract: The rotor for a squirrel-cage asynchronous rotating electrical machine comprises two compaction elements clamping a cylindrical magnetic mass, short-circuit rings facing the face of the compaction elements opposite that in contact with the magnetic mass, and conductive bars housed in recesses in the magnetic mass and distributed evenly over at least one diameter of the magnetic mass such that the short-circuit rings and the conductive bars form a squirrel cage. Retaining means distributed over at least one diameter of each short-circuit ring and over at least one diameter of each compaction element interact so as to secure the short-circuit rings and the compaction elements together, the pitch circle diameters of the retaining means on the rings and the compaction elements being smaller than the pitch circle diameter of the conductive bars.Type: GrantFiled: November 4, 2019Date of Patent: November 7, 2023Assignee: GE Energy Power Conversion Technology LimitedInventors: Christophe Galmiche, Remy Muller, Pierre Humbert

Patent number: 11231265Abstract: A system for measuring a bending deformation of a surface of a material which cooperates with a bending test machine to deform a test piece. The system includes a first portion with lateral teeth which bear against an upper surface of the test piece. A first load support connected to the lateral teeth applies a constant force towards the test piece. A second portion with a central tooth bears against the upper surface. A second load support connected to the central tooth applies a constant force oriented towards the test piece. A measuring device includes a deformation sensor having a first arm connected to the first portion, and a second arm connected to the second portion. The first arm and the second arm are separated from each other by a variable distance (?B) measured by the measuring device.Type: GrantFiled: February 20, 2020Date of Patent: January 25, 2022Assignee: SAFRAN AIRCRAFT ENGINESInventors: Pascal Noel Brossier, Pierre Bouissou, Joseph Henry, Remy Muller, Quentin Pujol D'Andrebo

Patent number: 11218044Abstract: Provided is a rotor for an asynchronous electrical machine having an end shaft that includes two half-shafts pressing against a cylindrical magnetic block and two short-circuit discs each placed between one different half-shaft and one of the ends of the cylindrical magnetic block. Each half-shaft includes at least one first means of retention, and each short-circuit disc includes on each of its faces at least one second means of retention and each end of the magnetic block includes at least one third means of retention, the first, second, and third means of retention mating with one another in such a way as to prevent the short-circuit discs from moving relative to the half-shafts and relative to the magnetic block.Type: GrantFiled: September 18, 2019Date of Patent: January 4, 2022Assignee: GE Energy Power Conversion Technology LimitedInventors: Christophe Galmiche, Remy Muller, Nicolas Velly
