A cage rotor of an asynchronous machine includes a magnetically conductive body having substantially axially running slots with conductors connected to end faces of the magnetically conductive body in an electrically conductive manner by short circuit rings. The short circuit rings have an outer side, an inner side, a front side, and a rear side. A supporting element made of a high-strength material is located at least radially within the short circuit rings, i.e. on the inner face, with the supporting element being connected to the short-circuit ring, at least in one section, with a material fit.

Cage rotor with support element

The invention relates to an arrangement for the damped bearing of a rotor shaft () of an electric machine. The invention also relates to an electric machine comprising a rotor shaft () and at least one such arrangement. The invention further relates to a method for the damped bearing of a rotor shaft () of such an electric machine. In order to provide an alternative for the damped bearing of a rotor shaft (), it is proposed that the arrangement has a bearing unit (), which can be arranged between the rotor shaft () and a housing () of the electric machine, and a damping element (), which can be arranged between the bearing unit () and the rotor shaft () or between the bearing unit () and the housing (), wherein the damping element () comprises a mesh of metal wire ().

Damped bearing of a rotor shaft

A method for selecting, processing and displaying data or data objects (toto) that are stored in a predetermined hierarchy in addressable memory locations of a data processing system. The hierarchy has a tree structure with a trunk and branched-off subdivisions. The method allows the association or common processing of the data or the data objects (toto) derived from listings on different hierarchical levels of the tree structure in a common table.
