  • Electric apparatus and its magnetic core of (100)[011] silicon-iron sheet made by rapid quenching method
    Patent number: 4427462
    Abstract: High-silicon steel sheets or ribbons having the crystal texture described by (100)[011] are used for the fabrication of magnetic cores of electrical machinery in such a way that the easy axes of magnetization <001> coincide with the directions of magnetic circuits or lines of magnetic flux. Magnetic cores of, for instance, electric motors or transformers can be remarkably improved in efficiency.
