Application characteristics of silicon electrical steel lamination

 For ultra-thin silicon steel sheets used as transformers, 0.35mm thick cold-rolled silicon steel sheets are usually used. According to the size of the ultra-thin silicon steel sheet core, the long pieces are cut directly and will be To a large extent, it will be overlapped into a "day" or a "mouth".  

 In order to reduce the eddy current of the silicon steel sheet, the thickness of the silicon steel sheet should be relatively thin, so that the spliced strips will appear narrower and the effect will be better. This not only reduces the eddy current loss, but also reduces its own temperature rise, and can also save the silicon steel sheet material.  

 Since the transformer is fabricated according to the principle of electromagnetic induction, two windings, one primary winding and one secondary winding, are wound on the closed ultra-thin silicon steel sheet iron core. When adding the AC power supply voltage to the original winding, it should also be noted that the original Rao flow will have alternating current.  

 Under the action of the magnetic potential, the alternating main magnetic flux is generated in the ultra-thin silicon steel sheet iron core, and the main magnetic flux passes through the ultra-thin silicon steel sheet iron core at the same time; at the same time, the electromagnetic induction effect is respectively That is, the induced electromotive force is generated in the primary and secondary windings.
