Abstract
The synchronous machine comprises a rotor provided with permanent magnets arranged for orthoradial magnetic induction and which are disposed around the axis in such a way that two adjacent magnets have counter-direction inductions, pole-pieces deviating the said induction so that it becomes radial to the periphery and each of the pole-pieces being formed of half-poles separated by a split pin applying each of the half-poles against the adjacent magnet, and wherein each magnet and each half-pole is in a single block in axial direction, the edges of the flanges ensuring the cohesion in radial direction.
