Transformaer Lamination 0.5mm Thickness EI Silicon Steel Core

This is because the sheet iron core can reduce another kind of iron loss "eddy current loss". When the transformer is working, there is an alternating current in the coil, and the magnetic flux it generates is of course alternating. This changing magnetic flux generates an induced current in the iron core. The induced current generated in the iron core circulates in a plane perpendicular to the direction of the magnetic flux, so it is called eddy current.

Eddy current losses also heat the iron core. In order to reduce the eddy current loss, the iron core of the transformer is made of silicon steel sheets insulated from each other, so that the eddy current in the narrow and long circuit passes through a smaller section to increase the resistance of the eddy current path; The increased resistivity of the material also plays a role in reducing eddy currents.

For the iron core of the transformer, cold-rolled silicon steel sheets with a thickness of 0.35mm are generally used. According to the size of the iron core, it is cut into long pieces, and then overlapped to form a Japanese character or mouth shape.

In theory, if the thickness of the silicon steel sheet is thinner to reduce the eddy current, the narrower the spliced ​​strips, the better the effect. This not only reduces the eddy current loss, lowers the temperature rise, but also saves the material of silicon steel sheet. But in fact when making silicon steel sheet iron core. It is not just from the above-mentioned favorable factors, because the production of the iron core in that way will greatly increase the working hours and reduce the effective cross section of the iron core.

Therefore, when using silicon steel sheet to make the transformer core, we should weigh the pros and cons from the specific situation and choose the best size. Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of silicon (silicon also called silicon) steel, and its silicon content is 0.8 ~ 4.8%.
