摘要
The rotor for a squirrel-cage asynchronous rotating electrical machine comprises two compaction elements clamping a cylindrical magnetic mass, short-circuit rings facing the face of the compaction elements opposite that in contact with the magnetic mass, and conductive bars housed in recesses in the magnetic mass and distributed evenly over at least one diameter of the magnetic mass such that the short-circuit rings and the conductive bars form a squirrel cage.Retaining means distributed over at least one diameter of each short-circuit ring and over at least one diameter of each compaction element interact so as to secure the short-circuit rings and the compaction elements together, the pitch circle diameters of the retaining means on the rings and the compaction elements being smaller than the pitch circle diameter of the conductive bars.
