Electrical steel sheets play an important role in magnetic circuit core design of electrical machines. Electrical steel are graded depending on value of specific total loss (PS). According to the present knowledge thePSloss consists of three components: hysteresis loss and both classical and additional eddy current loss components. Magnetic properties depend on direction of magnetization i.e. magnetocrystalline anisotropy. The determination of the specific power loss separation of electrical steel sheets in different direction to rolling direction have been performed using non-standard single sheet tester. Specific total loss was separated into hysteresis, eddy current and excess loss components. The relationship between the hysteresis and additional loss components and the magnetic anisotropy was analyzed. The aim of this paper is to provide a contribution to the better understanding of specific total loss in electrical steel with Goss texture.

The compact strip processing technology and the technologies for conventional grain oriented electrical steels were used to process the low cost grain-oriented electrical steel successfully, in which the reheating temperature for hot rolling was about 1150 oC, and strong Goss texture was obtained after the secondary recrystallization. It is indicated that the density of inhibitor particles produced under the condition of low temperature hot rolling was high enough to induce the necessary secondary recrystallization during final annealing, so that many Goss grains could grow. The mis-orientations of Goss grains to the recrystallization matrix were calculated and observed. High angle boundaries enveloped frequently Goss grains, while the growth of other grains would have the possibility to meet low angle boundaries or low mobile boundaries. Goss grains neighboring larger size grains might be protected by the further precipitation of inhibitor particles in high angel boundaries during the temperature rising stage of the secondary recrystallization and survived somehow after the growth competition.
