Abstract: The invention relates to a method for the production of a soft magnetic core for generators and generator with a core of this type. To produce a core, a plurality of magnetically activated and/or magnetically activatable textured laminations is produced from a CoFeV alloy. This plurality of laminations is then stacked to form a core assembly. Then the core assembly, if consisting of magnetically activatable laminations, is magnetically activated. Finally, the magnetically activated core assembly is eroded to produce a soft magnetic core. A core of this type is suitable for a generator with a stator and a rotor for high-speed aviation turbines, the laminations in the core assembly being oriented in different texture directions relative to one another.
