The invention of electrical machines has enabled human to do their chores with easier and more comfortable way. Presently, electromagnetic technology is improving day by day and most of the current electrical machines require the magnetic cores to operate at higher frequency to meet the demand of high–speed performance in catching up the aggressive technological evolution. On top of that, the researchers and engineers are aiming for the lower loss magnetic material in order to obtain the high efficiency of the electrical machines. Magnetic properties of soft magnetic material have been actively studied under 1-D and 2-D magnetic flux excitations to estimate the total core loss produced by the material during the magnetisation of electrical machine. In the past years, soft magnetic composite (SMC) materials were used in designing flexible electromagnetic devices due to their unique properties such as magnetic isotropy that consists of small insulated iron particles with low eddy current. SMC materials are suitable for these applications because of their properties like high electrical resistivity which leads to the low eddy current loss, and 3-D magnetic isotropy which provides great design flexibility of various electromagnetic devices. In this project, the magnetic properties of a new SMC material, SOMALOY 700 (5P) from Hoganas has been studied since it offers low core loss during magnetisation. The magnetic properties should be properly measured as there are some variations of vector flux density in the rotating machine. 1-D and 2-D magnetic measurements are conducted by controlling magnetic flux densities to be in various shapes by using LabVIEW software. The x-, y- and z-axes of magnetic flux densities were generated by using the 3-D magnetic property testing system. The results of the measurement are analysed by using the Mathcad software before being compared to other materials. The performances of this material at wide range of frequency are exhibited by plotting the loss curves in the same graph. The finding indicates that the magnetisation at 1000 Hz contributes higher core loss for all types of magnetic flux excitation. At high frequency, the total core losses are dominated by hysteresis loss. The core loss curves with clockwise and anti-clockwise directions presented the similar rotational core loss. Besides that, the elliptical core loss with Bₓ and Bᵧ as the major axes are similar in magnitude. All types of core losses are analysed and verified by comparing them with the calculation theory. The accuracy of the core loss has been obtained by considering Mean Absolute Percentage Error (MAPE) to compute the percentage error of the measurement. The details of SOMALOY 700 (5P) material provide good information to engineers in designing electrical machine at different variation of frequencies.","abstract_html":"The everyday lives of people have been dramatically changed due to the evolution of technology.
