  • Publication number: 20180287472
    Abstract: A rotor for an asynchronous machine has a laminated core and a short-circuit cage at least partially integrated in the laminated core. The short-circuit cage is designed with rods having or consisting of a first electrically conductive material and short-circuit rings having or consisting of a second electrically conductive material. At least one of the short-circuit rings is designed with a support ring, and each support ring is designed as a structure interlockingly and/or integrally cast onto or into the associated short-circuit ring.
    Type: Application

  • Publication number: 20180287468
    Abstract: A rotor for an asynchronous machine includes a laminated core and a short-circuit cage at least partially integrated in the laminated core. The short-circuit cage is designed with rods having or consisting of a first electrically conductive material and with short-circuit rings having or consisting of a second electrically conductive material. The short-circuit rings are indirectly or directly frictionally welded to the rods.

  • Publication number: 20180287444
    Abstract: A rotor for an asynchronous machine includes a laminated core and a short-circuit cage which is at least partially integrated in the laminated core, in which the short-circuit cage is made of rods having or made from a first electrically conductive material and short-circuit rings having or made from a second electrically conductive material. A support ring is provided on at least one of the short-circuit rings and is in mechanical contact therewith. The at least one short-circuit ring and/or the support ring has a contour for creating the mechanical contact, and the mechanical contact is a press fit.
