Abstract (en)

[origin: WO2018115678A1] A rotating electrical machine comprising a rotor (1) mounted on a shaft, the rotor (1) being designed to be rotated with respect to the stator, the rotor (1) comprising: longitudinal cavities for receiving at least one permanent magnet (10) and forming magnetic poles of the rotor (1), each pole being formed by two adjacent cavities having a V-shaped or U-shaped profile in a plane orthogonal to the axis (2) in which the shaft of the electrical machine is located; a spring (12) comprising two arms (120, 120') connected to a connection portion (123) and forming an axial stop, the two arms (120, 120') being inserted in each of the cavities of a pole in order to exert a force holding the magnets (10) on the outer edge of the rotor (1).
