A method for classifying electrical sheet is produced. The electrical sheet is used to produce an electrical machine and is available in the form of a strip roll wherein a magnetic flux that changes over time and that causes a shape change of the strip roll and magnetic losses is produced in the strip roll by means of an excitation winding fed by a feeding device, the shape change and/or the magnetic losses are measured by means of a measuring device and the measurement signal obtained is fed to an evaluation device, and the evaluation device categorizes the electrical sheet in regard to noise emission and/or magnetic losses using the measurement signal. |
