Zusammenfassung:Rotor for an asynchronous electrical machine comprising a magnetic ring (20) comprising a plurality of layers of ferromagnetic metal sheets stacked axially and a squirrel cage (22) having a plurality of conductive elements (24) regularly distributed over the periphery of the magnetic ring (20) and each having two opposite ends extending axially beyond the magnetic ring (20) and each connected to a short-circuit crown (26; 28), arranged axially on either side of the magnetic ring (20) and intended to connect the ends of the conductive elements (24) electrically. The rotor is segmented circumferentially into at least two rotor segments (20a).
