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 anisotropy of magnetic properties in non-oriented electrical steel sheets can be evaluated by measuring Epstein specimens in the radial directions. The magnetic properties measured on ring cores are practically equal to the approximate values of magnetic properties determined by Epstein specimens in the radial directions. Non-oriented electrical steel sheets with anisotropy are not desirable for motors but are suitable for transformers and fluorescent lamp ballasts. The core loss and magnetic induction as measured with ring specimens are better with non-oriented electrical steel sheets with anisotropy than with non-oriented electrical steel sheets with random crystallographic orientation. This phenomenon depends on the texture change of the product.
