摘要：

The electrical and magnetic properties of the core composed of Electrolytic iron particles with different shapes (needle shape, flakey shape, and spherical shape) were investigated. In the frequency range below several tens kHz which the hysteresis loss is mainly dominant, the core loss became smaller in the order of the flakey particles, needle particles, and spherical particles. On the other hand, in the frequency range between several hundred kHz to several MHz which the eddy current loss is mainly dominant, the core loss of the flakey particles was the smallest of all particles. These results demonstrate that cross-sectional shape and area of particle in core play one of the important roles in the reduction of core loss. © 2024 The Institute of Electrical Engineers of Japan.
