Abstract (en)

[origin: EP2521143A1] The material has magnetically effective partial components (10a) that are cellularly formed and provided with pore structures (12a). The pore structures are partially opened and/or closed, and exhibit an effect with hard magnetic or soft-magnetic characteristics. The pore structures are mechanically and/or thermally treated to realize texturing, and the partial components are designed in a self-supporting manner. The partial components absorb electromagnetic vibrations, and filling mediums e.g. oil or oily liquid, are provided within the pore structures. An independent claim is also included for a system comprising an electric motor.
