PERMANENT MAGNET ROTOR WITH COMPLETE AMORTISSEUR Abstract of the Disclosure A rotor for a permanent magnet machine comprises laminated pole pieces held in position by interpolar nonmag- netic clamp pieces bolted to a solid rotor core having central portions with a polygonal cross section. Magnets are situated between the pole pieces and the faces of the central portion of the rotor and held in place by the clamping of the pole pieces. Pole piece bars are situated in axial extending apertures circumferentially arranged at the periphery of the pole pieces. Clamp piece bars are situated in channels in the clamp pieces. End rings elec- trically and structurally connect the clamp piece bars and pole piece bars at either axial end of the rotor forming a uniformly distributed starting cage.
