Zusammenfassung:Various embodiments of the teachings herein include an electric motor. In some embodiments, the motor includes: a stator; and a moving component comprising an iron-based soft-magnetic structural material including crystallites of a ferromagnetic iron-based alloy separated by grain boundaries, wherein there is interlayer-free contact between the crystallites at grain boundaries. The structural material comprises ceramic fibers. A content of the ceramic fibers is between 0.2% and 10% by volume. An aspect ratio of the ceramic fibers is less than 0.1.
