Magnetodielectrics as Materials for Magnetic Cores in AC Applications

Abstract

The properties of some magnetodielectric materials, based on iron powder and epoxy resin, are discussed. Particular attention is paid to the effect of the materials upon magnetic properties, hysteresis loss especially. Based on experimental evidence, component phase structure models and formulae for calculating magnetic, electric, and thermal parameters are given. Applications are suggested, taking into account the functions to be performed by magnetic cores in the magnetic circuits of an electrical machine. PM/0260
