Abstract
A method for producing a cage rotor for an asynchronous machine has the following steps: providing a laminated rotor core made of a plurality of stacked rotor laminations which each have a plurality of rotor lamination grooves distributed in the circumferential direction; placing rod-shaped wire bundles, which are each made up of a plurality of wires, into the rotor lamination grooves; rotating the individual rotor laminations relative to each other, thereby deforming the wire bundles; placing short-circuit rings on both end faces of the laminated rotor core, and connecting the wire bundles to the short-circuit rings.
