摘要： 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.

摘要： An active part for an electric machine can be configured as a stator or a rotor and includes at least two slots for arranging an electric coil winding of an electric coil. Arranged between the two slots is a crosspiece which is made of a material for conducting a magnetic flux through the electric coil which surrounds the crosspiece. The material has, at least in one area, magnetic anisotropy with an easy magnetization axis, which is oriented parallel or at least at an angle of less than 25° with respect to a coil axis of the coil, and a hard magnetization axis. The crosspiece is configured to form for each of the slots a slot wall which contains the material. The crosspiece includes a core which is made of an isotropic soft-magnetic material.
