Squirrel-cage rotor, and asynchronous motor comprising such a rotor

An electric machine, comprising a stator and a rotor

• wherein the rotor extends along an axis of rotation and comprises:
• a short-circuit cage comprising at least one bar;
• and
• at least one first electrical short-circuit ring, the or each bar comprising a first end part, the first end part being connected to the first short-circuit ring electrically by a first connection and radially with respect to the axis of rotation, wherein the or each first connection between a respective first end part and the first short-circuit ring comprises a plurality of flexible electrically conductive blades, the flexible blades of a respective connection being disposed along at least half of the periphery, in a transverse plane perpendicular to the axis of rotation, of the corresponding end part.
