Rotor having a squirrel cage

A rotor of a rotary dynamoelectric machine, said rotor comprising:

• a magnetically conductive body including slots that are distributed around a circumference and substantially run axially, said magnetically conductive body including a base body and adjacent to the base body on each end face of the base body at least two further additional bodies, with a first one of the at least two further additional bodies axially directly adjoining the end face of the base body and a second one of the at least two further additional bodies axially adjoining the first one of the at least two further additional bodies, wherein the slots have on each of the end faces of the magnetically conductive body radially exposed slot sections which extend in the second one of the at least two further additional bodies and only for a predetermined axial section in the first one of the at least two further additional bodies, said base body formed by laminations and designed axially continuous or formed of partial base laminated cores, with the first one of the at least two further additional bodies made of homogeneous material and having an axial thickness which corresponds to a multiple of a lamination thickness;
• a squirrel cage including electrical conductors arranged in the slots such that the radially exposed slot sections enable the conductors to move radially outward;
• and
• short-circuit rings arranged on the end faces of the rotor to electrically contact the conductors.
