Abstract:
A rotor for an electric machine is mounted for rotation about an axis and includes a plurality of permanent magnets placed on a radial outer surface of the rotor for forming at least one magnetic pole pair. An anisotropically-soft sintered magnetic material having an easy direction and a hard direction is located in at least one section of the rotor radially further inward than the plurality of permanent magnets.
