Textures of dynamo steel sheets

Dynamo steel sheets should have isotropic magnetic properties; however, different magnetic measurements have shown that the majority of the dynamo sheets have certain anisotropic properties. The main reason of this anisotropy is an occurrence of certain textures in the dynamo sheets. The crystallographic research allowing determination of the dynamo sheet textures is described in the paper. For some typical dynamo sheets the basic textures and their volume fraction of the total sheet sample are presented. The properties of the determined textures are applied in the method which gives us possibilities to take into account the anisotropic properties more accurately than hitherto. In the proposed method, iron particles of the dynamo sheets are treated as grains which have three axes of the easy magnetization unlike to existing approaches. The influence of the texture type on the flux density changes is discussed in the paper.
