Characteristics of soft magnetic composite material under rotating magnetic fluxes

Abstract This paper reports the measurement of magnetic properties of the soft magnetic composite material SOMALOY TM 500 in a square sample under different patterns of flux density with 2D magnetic excitations. The test system, principle of measurement, magnetic power loss calculation, and methods of correction for misalignment of H surface sensing coils are presented. The experimental results show that although nominally isotropic, the SOMALOY TM 500 sample exhibits some anisotropy. The results are useful in the design and performance analysis of rotating electrical machines.
