Short circuit rotor for an electric motor, in particular an asynchronous motor, electric motor, and method for producing a squirrel cage rotor

摘要

The present invention relates to squirrel-cage rotors (R) for an electric motor, in particular an asynchronous motor, having an axis of rotation (4) comprising at least one first shorting ring (1), an axially spaced second shorting ring (1a), and a shorting bar (2) Shorting bar (2) has a portion (21) with a first cross section (A1) and a terminal body segment (22) with a second cross section (A2), wherein the second cross section (A2) is greater than the first cross section (A1), wherein the Shorting rings (1) have an inner side (11) facing the shorting bar (2), wherein the connecting body segment (22) is connected to the inner side (11) of one of the shorting rings (1 or 1a), an electric motor with a squirrel cage rotor according to the invention, and a Method for producing a squirrel cage rotor according to the invention.
