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.

A high speed synchronous machine rotor comprising: a plurality of magnets equally spaced circumferentially and angularly alternating with a plurality of poles, each pole including two half-pole pieces, adjacent radial faces of said half-pole pieces being spaced apart; means for restraining displacement of said poles and magnets in an axial direction; first means for restraining radial displacement of said poles and magnets, said first means including a split pin disposed in a recess formed in said adjacent faces of said half-pole pieces of each pole, said pin having a split positioned radially within the recess, said pin forcing angularly outward opposite faces of said half-pole pieces against said magnets thereby providing cohesion between the magnets and pole pieces of said rotor; and second radial restraining means including axially spaced flange members having continuous edges coacting with corresponding outwardly extending shoulders formed on said half pole-piece.
