Measurement of some magnetic properties of electrical steel sheets under axial magnetization

Improvement in properties of electrical machines can be obtained by proper design which requires precise simulation and knowledge about properties of used magnetic materials. One very important property is specific power loss. To analyze, the specific power loss of electrical steel is helpful to separate the loss into three components. It is commonly accepted that the specific power loss consists of three components: hysteresis loss component and both classical and additional eddy current loss components. All three components are dependent on degree of texture and show different trends as the magnetic flux density increases. The aim of the paper is to provide a contribution to the better understanding of magnetic specific power loss in electrical steel sheets with different degree of Goss texture.
