摘要： A method for producing a rotor of an asynchronous machine includes providing a rotor lamination stack having grooves extending parallel to a rotor axis of the rotor, inserting conductor rods into the grooves such that the conductor rods protrude from end faces of the rotor lamination stack, wherein a twisting tool is placed at each of the end faces onto the protruding conductor rods and the twisting tools are twisted relative to each other, where the parallel grooves with the corresponding conductor rods also extend obliquely after the twisting and where the twisting tools are formed such that the protruding conductor rods remain parallel to the rotor axis when an oblique profile of the stack is produced, removing the twisting tools, providing first and second short-circuit washers, and axially pressing the short-circuit washers onto the conductor rods projecting perpendicularly from the end face of the rotor lamination stack.

摘要： A squirrel cage rotor for an asynchronous machine includes a magnetically conductive main body which is mounted for rotation about an axis and includes electric conductors in substantially axially extending slots. The electric conductors are electrically contacted by short-circuit rings which are located on end faces of the magnetic main body and configured as a thermosiphon.
