  • Rotor for an electric machine, the rotor has short circuit bars, short circuit ring, and support disc of different materials
    Patent number: 10886825
    Abstract: A rotor for an electric machine. A laminated core with a plurality of short-circuit bars that pass through it and are joined at both ends by way of a respective short-circuit ring. A support disc, which is made of a material that has a higher strength than the material of the short-circuit ring, is axially arranged at each short-circuit ring.
    Type: Grant
    Filed: April 13, 2018
    Date of Patent: January 5, 2021
    Assignee: AUDI AG
    Inventors: Korbinian Weber, Jörg Rücker, Peter Suess
  • Method for producing a short circuit rotor and short circuit rotor
    Patent number: 10770957
    Abstract: A method for producing a short circuit rotor, by providing a laminated rotor core with through openings for shorting bars of a squirrel cage as well as providing the shorting bars; inserting of the shorting bars into the through openings such that an axial overhang remains on both sides; placing a main disk with through openings on both sides for the shorting bars, whose axial length corresponds to the overhang, as well as an edge disk immediately adjacent to the main disk and the ends of the shorting bars. The main disk and the edge disk form a shorting ring of the squirrel cage, and the main disk and the edge disk are welded by radially encircling electron beam welding.
