1. A rotating electrical machine, comprising:
a stator;
a shaft centered in the stator; and
a first cylindrical magnetic mass and a second cylindrical magnetic mass, the first cylindrical magnetic mass and the second cylindrical magnetic mass enclosing the shaft and arranged in series on the shaft, the first cylindrical magnetic mass and the second cylindrical magnetic mass being separated by an air gap, the stator including coils, each coil being opposite to the two cylindrical magnetic masses, each cylindrical magnetic mass comprising a stack of compacted laminated magnetic sheets, a first fastener configured to fix the first cylindrical magnetic mass and the shaft, and a second fastener configured to fix the second cylindrical magnetic mass and the shaft, a diameter of the first cylindrical mass being equal to a diameter of the second cylindrical mass, the rotating electrical machine further comprising a hollow cylindrical support part, the shaft comprising a first half shaft and a second half shaft, the cylindrical support part being inserted between the first half shaft and the second half shaft, and the first cylindrical magnetic mass and the second cylindrical magnetic mass being fixed on the periphery of the cylindrical support part,
the first and second fasteners comprising the hollow cylindrical support part.
