Abstract
A rotor of an asynchronous machine with a cage rotor includes a laminated core formed from a plurality of partial laminated cores. The laminated core has substantially axially extending conductors arranged in slots in the laminated core. The conductors include at least two materials of different electrical conductivities, such that a material with a higher electrical conductivity surrounds a material with a lower electrical conductivity by at least 65% in a circumferential direction.
