Abstract :
The total core loss at 15 kG induction of different types of nonoriented lamination steel is described empirically as a single function of thickness, grain size, resistivity, and a quantity related to the preferred orientation of the material. This texture-related quantity is the induction at 30 oersted, B30, divided by the saturation induction, BS. In addition, a linear effect of oxygen content on core loss is described for a more restricted group of materials.
