Abstract:

Studying the dependence of the specific magnetic losses on the frequency and induction of magnetically soft electricotechnical materials has shown the inefficiency of the conventional method of separation of the specific magnetic losses into components. For example, according to the conventional technique, one can find that there are ranges of frequencies where the total magnetic losses are smaller than the hysteresis component; besides, at comparatively high inductions it is possible to reduce the dynamic component of magnetic losses to virtually zero. The investigation carried out allowed us to suggest a new method of separation of magnetic losses into components taking into account a frequency dependence of the hysteresis losses. The results of the analysis of the magnetic-loss components in the context of the suggested method for ribbons of rapidly quenched soft magnetic alloys allowed us to eliminate the contradictions revealed. Besides, they have shown that the formation of a low-frequency resonance peak of absorption in the region of displacement of 180 degrees domain walls is mainly caused by the frequency-dependent component of the hysteresis losses, whereas in the interval of inductions where the processes of displacement of 90 degrees domain walls are active, this formation is caused by both the dynamic and frequency-dependent hysteresis components of magnetic losses.
