Abstract：To explore the application potential of soft magnetic composite(SMC)materials in the cores of high-frequency motors,this study takes Somaloy 700 3P,a soft magnetic composite material produced by Höganäs AB,as the research object.In accordance with the IEC 60404 standard,the core losses of the material were measured under the conditions of magnetic flux densities of 0.5 T and 1 T,and a frequency range of 100-1 000 Hz.The experimental results show that the measured core losses of Somaloy 700 3P are basically consistent with the values provided by the manufacturer and when the frequency is higher than 500 Hz,the core loss of Somaloy 700 3P is significantly lower than that of non-oriented electrical steel.The experimental results prove that Somaloy 700 3P soft magnetic composite material has better core performance under high-frequency operating conditions.
