Abstract
Provided is a rotor for an asynchronous rotating electrical machine that includes a cylindrical magnetic mass, two short-circuit disks, a non-through shaft that includes two half-shafts tightly holding the cylindrical magnetic mass and the two short-circuit disks each sandwiched between the half-shafts and one of the ends of the magnetic mass, and conducting bars housed inside the magnetic mass and distributed uniformly along at least one diameter of the magnetic mass such that the short-circuit disks and the conducting bars form a squirrel cage, and the half-shafts, the short-circuit disks and the magnetic mass form a gas-tight envelope.
