The main role of three -phase EI lamination in application
Jan 03, 2019

The three -phase EI lamination is the main component of the transformer, and the transformer actually works under the AC state, and its power loss is not only on the resistance of the coil, but also under the alternating current magnetization among the three -phase EI lamination. In general, the power loss in a three-phase EI laminate will be called "iron loss".

The iron loss of a three -phase EI lamination is mainly caused by two reasons, one of which is actually referred to as "hysteresis loss" and the other is actually "eddy current loss". The hysteresis loss is that the three-phase EI laminate is in the process of magnetization. Insofar as it is in a large degree, it will directly cause iron loss due to its hysteresis. The size and material of this loss The size of the area surrounded by hysteresis loops is actually proportional.

Then, the hysteresis loop of the three -phase EI lamination is also very narrow, so as far as it is concerned, it is actually used as a three-phase EI laminate to a large extent. In fact, the hysteresis loss of the chip is relatively small, which can greatly reduce the degree of heat generation.

The reason why the three -phase EI lamination is made of monolithic silicon steel, it has to be processed into a sheet shape, and to a large extent, it will reduce another type of iron loss, which means "eddy current loss". When the transformer is working, there is actually an alternating current in the coil, and the magnetic flux generated by it is of course alternating.
