It is mainly composed of silicon (about 3%-5%) and stainless steel (low carbon steel), usually made by cold rolling process, with low hysteresis loss and high magnetic permeability. In the process of processing silicon steel sheet, in order to shorten the magnetic flux path, reduce hysteresis loss, refine the eddy current channel, reduce eddy current loss, and thus improve the efficiency of motors or transformers, silicon steel sheets need to be laminated.
