A rotor for an electric motor comprising at least: - a rotor shaft, the rotor shaft extending along a central axis of the rotor, - at least two squirrel cages, each squirrel cage comprising at least two conductor bars and at least two shorting rings, the conductor bars being interconnected by shorting rings, each squirrel cage being coaxial with the central axis, - a stack of sheets, each sheet of the stack of sheets comprising a central bore for the passage of the rotor shaft and peripheral bores for the passage of the conductor bars, - the squirrel cages being interleaved with each other, for each squirrel cage, at least one of the shorting rings being arranged between the conductor bars of another squirrel cage, - the squirrel cages being angularly offset from each other by a constant angle (α), - the squirrel cages being electrically independent of each other, - all conductor bars of all squirrel cages being equidistant from the central axis of the rotor, - the stack of sheets being cylindrical in shape and comprising a central part and two ends (211B, 211C), - the central part of the stack of sheets comprising magnetic sheets, - the central part of the stack of sheets being completely traversed by the rotor shaft and by the conductor bars, - each end (211B, 211C) of the stack of sheets comprising a pile of sheets (210b, 210c) alternating between insulating sheets and shorting sheets, - the pile of sheets (210b, 210c) of each of the two ends (211B, 211C) of the stack of sheets being implemented in the same order along the central axis of the rotor, - each end (211B, 211C) of the stack of sheets comprising as many groups of shorting sheets as the rotor comprises squirrel cages, - two adjacent sets of shorting sheets being angularly offset by an angle equal to the angle (α) of offset of the squirrel cages, and - the shorting sheets comprising apertures, the apertures housing the shorting rings. - a rotor shaft, the rotor shaft extending along a central axis of the rotor, - at least two squirrel cages, each squirrel cage comprising at least two conductor bars and at least two shorting rings, the conductor bars being interconnected by shorting rings, each squirrel cage being coaxial with the central axis, - a stack of sheets, each sheet of the stack of sheets comprising a central bore for the passage of the rotor shaft and peripheral bores for the passage of the conductor bars, - the squirrel cages being interleaved with each other, for each squirrel cage, at least one of the shorting rings being arranged between the conductor bars of another squirrel cage, - the squirrel cages being angularly offset from each other by a constant angle (α), - the squirrel cages being electrically independent of each other, - all conductor bars of all squirrel cages being equidistant from the central axis of the rotor, - the stack of sheets being cylindrical in shape and comprising a central part and two ends (211B, 211C), - the central part of the stack of sheets comprising magnetic sheets, - the central part of the stack of sheets being completely traversed by the rotor shaft and by the conductor bars, - each end (211B, 211C) of the stack of sheets comprising a pile of sheets (210b, 210c) alternating between insulating sheets and shorting sheets, - the pile of sheets (210b, 210c) of each of the two ends (211B, 211C) of the stack of sheets being implemented in the same order along the central axis of the rotor, - each end (211B, 211C) of the stack of sheets comprising as many groups of shorting sheets as the rotor comprises squirrel cages, - two adjacent sets of shorting sheets being angularly offset by an angle equal to the angle (α) of offset of the squirrel cages, and - the shorting sheets comprising apertures, the apertures housing the shorting rings.
