Abstract

A squirrel cage rotor having a shaft, a rotor plate stack with rotor bars arranged in the interior thereof, and cage rings, wherein at least one part of a cage ring includes a disk stack, which is constituted as a layered structure of disks with cut-outs, through which the ends of the rotor bars project out of the rotor plate stack. Adjoining disks in the disk stack are mutually spaced, and form a gap. The clearance between two adjoining disks, resulting from the gap, is constituted by moldings which are arranged on the disks wherein, in the gap, at least in the region of the moldings, a joint connection is provided.
