Abstract: The invention relates to a cage rotor (1) for an electrical asynchronous machine, which comprises a disk pack (7) of a plurality of laminate plates (5) stacked side by side in the axial direction as well as a short-circuiting cage (9). The short-circuiting bars (11) of the short-circuiting cage (9) extend in the axial direction through the disk pack (7) and are in each case connected to end faces of the disk pack (7) by a short-circuiting ring (13). The cage rotor is characterized in that tie rods (16) are arranged on the disk pack, which have a higher mechanical strength than the short-circuiting bars (11) and project from the end faces of the disk pack (7) in the axial direction and protrude at least partially into at least one of the short-circuiting rings (13). The tie rods (16) can be, for example, stabilizing bars (17) which extend in the axial direction through the disk pack (7). In this way, the tie rods (16) can stabilize the short-circuiting rings (13), which are typically made of mechanically soft material, against, for example, centrifugal forces occurring at high rotational speeds. If the tie rods (16) are configured as stabilizing bars (17) in the form of hollow pipes, they can additionally serve as cooling channels. Projecting end regions (21) can be suitably bent or shaped to form blades in order to circulate cooling fluid or to convey it through the hollow stabilizing bars (17).
