Abstract After copper losses, core losses are generally the second largest component of power loss or inefficiency in the brushless motor, although their significance may become overriding at very high speeds. They arise from the variation of magnetic flux-density throughout the core, particularly the stator core.

Core Losses Separation of Amorphous Alloy Core
Materials Science Forum, 2016In this paper, the core losses of Fe80Si9B11, Fe78Si9B13 amorphous alloy cores were separated to investigate the behaviors of hysteresis loss, eddy current loss and additional loss in high frequency range. The results showed that the losses of amorphous alloy core were mainly composed of hysteresis loss in low frequency. With the increase of frequency,

Apparent core losses and core losses in five-limb amorphous transformer of 160 kVA
IEEE Transactions on Magnetics, 1998Significant modifications of the shape of magnetic flux in columns and yokes were observed in the magnetic circuit of four amorphous cores used in a 3-phase transformer. The magnetic losses measured experimentally were significantly higher than the ones calculated theoretically.

Deconvolution of core loss electron energy loss spectra
2009Experimental electron energy loss spectra (EELS) are related to inelastic scattering events in the sample by the so called single scattering distribution S(E) [1] (the differential cross section after integration in the detector acceptance angle). The relationship between the experimental spectrum and its S(E) is complicated because of several effects,

Enhancement of resolution in core-loss and low-loss spectroscopy in a monochromated microscope
Ultramicroscopy, 2006The significant enhancement of the energy resolution in the new generation of commercially available monochromated transmission electron microscopes presents new challenges in term of selecting the correct experimental conditions and understanding the various effects that can potentially influence the quality of the EELS data.

Mathematical descriptions of core losses
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1953This paper presents results so far achieved by the writers in endeavoring to gain an understanding of the factors controlling a-c core losses in modern magnetic materials. Losses have been measured on a number of cores over a range of frequencies and at flux densities in the middle portions of the magnetization curves.

Error analysis of high frequency core loss measurement for low-permeability low-loss magnetic cores
2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016Magnetic components significantly contribute to the dissipated loss in power electronic converters. Measuring the true value of dissipated power in these components is highly desirable, since it can be used to verify the optimum design of these components.
