EN Magnetization processes in typical dynamo steel sheets can have different character. In parts of the dynamo sheets, which refer to the stator core of induction motors, the magnetization process has rotational character, first of all elliptical character. The second kind of magnetization processes, the axial magnetization occurs mainly in stator teeth. It is worth underlining that dynamo sheets are also applied in cores of small power transformers. The paper deals with power losses depending on the frequency and on the maximum value of the flux density in dynamo sheets. In the analysis, the anisotropic properties of these sheets were taken into consideration. Special attention was paid to the losses depending on the magnetization direction on the sheet plane. Measured power losses in selected dynamo sheets were compared with results obtained on the basis of analytical formulas.
