Inventor(s) include Brandl, Konrad; Deim, Sybille; Krompasky, Erik; and Rauch, Hartmut.
The application for the patent was published on Aug. 29, under issue no. 35/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for producing a squirrel-cage rotor (10) of a dynamo-electric machine (1), in particular an asynchronous machine, comprising the following steps, - positioning a cylindrical, magnetically conductive body in a rotationally-fixed manner, in particular a laminated core (22), having grooves (30) extending substantially axially on the outer circumference, on a shaft (17), - inserting conductor rods (11) into the grooves (30), in such a way as to result in axial projections (32) of the conductor rods (11) at the two end faces (31) of the cylindrical, magnetically conductive body, - coaxially positioning a short-circuit ring (12) consisting of at least two parts, in particular three parts, in the radial direction, on the shaft (17) at a pre-determinable axial distance (16) from the end face (31) of the magnetically-conductive body, - electrically contacting the short-circuit ring (12) with the axial projections (32) of the conductor rods (11) which each protrude from the end faces (31) of the magnetically conductive body."
The patent application was internationally filed on Nov. 21, 2023, under International application No.PCT/EP2023/082483.
