ABSTRACT:
In a squirrel-cage rotor for an asynchronous machine, having a laminated core (2) which is mounted on the shaft (1), held together at both ends by press rings and is intended for accommodating the cage bars (3), the latter are respectively permanently connected to a short-circuiting ring (4) outside the laminated core (2). Each short-circuiting ring (4) is supported in the radial direction by a support ring (6) fixed on the shaft. In order to couple the cage head to the rotor body over the entire speed range of the machine for the purpose of suppressing natural vibrations, the two press rings are axially spaced from the laminated core (2) and simultaneously form the support ring (6) for the short-circuiting ring (4). In order to ensure the ventilation of the winding overhang, there are provided between the end face of the laminated core (2) and the support ring (6) spacer webs (7) which are preferably constructed in one piece with the support ring (6).
