Short-circuit ring for an electrical asynchronous machine, composed of partial ring segments

A rotor for an electrical asynchronous machine, comprising:

• a rotor body, wherein on an outer side of which there are a number of grooves in a longitudinal direction, and wherein on the rotor body there is situated a rotor cage having oblong rods and circular short-circuit rings;
• wherein each of the circular short-circuit rings include multiple partial ring segments that form the circular short-circuit ring, wherein the short-circuit ring has, along the circumference of the short-circuit ring, a multiplicity of recesses extending in the axial direction, into which the oblong rods of the rotor cage of the asynchronous machine are selectively placed,
• wherein the oblong rods are placed into grooves of the rotor body and axially protrude therefrom, and
• wherein the short-circuit rings are situated on opposite axial ends of the rotor body,
• wherein the multiple partial ring segments each have a yoke portion radially inside of the recesses,
• wherein each of the multiple partial ring segments has, on its side oriented toward an interior of the rotor and/or on its side oriented towards an exterior of the rotor, a surface in a shape of a partial cylinder arc, so that a number of the multiple partial ring segments situated alongside one another in a circumferential direction form as a whole the short-circuit ring having a circular or cylindrical geometry,
• wherein the partial ring segments are configured as thin sheets, and multiple thin sheets are stacked one after the other in the axial direction of the short-circuit ring, and
• wherein the thin sheets in different planes in the axial direction are configured to be offset relative to one another in the circumferential direction.
