Since silicon steel has the above advantages, why not use the whole silicon steel as the iron core and process it into a sheet? This is because the sheet iron core can reduce another iron loss – “eddy current loss”. When the transformer works, there is alternating current in the coil, and the magnetic flux generated by it is of course alternating. This changing magnetic flux produces an induced current in the iron core. The induced current generated in the iron core flows in a ring in a plane perpendicular to the magnetic flux direction, so it is called eddy current. Eddy current losses also heat the core. In order to reduce the eddy current loss, the iron core of the transformer is stacked with silicon steel sheets insulated from each other, so that the eddy current passes through a small section in the narrow and long circuit, so as to increase the resistance on the eddy current path; At the same time, the silicon in silicon steel increases the resistivity of the material and reduces the eddy current.

The common mode inductor using nanocrystalline core material can well suppress the peak voltage, protect sensitive components, and reduce the motor shaft voltage. Because of the unique characteristics of nanocrystalline core, it has been well used in some high-power system industries. Electric energy meter, power meter, ammeter, electric measuring equipment and other instrument fields. Various power current transformers in power transmission and distribution monitoring system. Leakage protection, relay protection, servo motor protection, fire monitoring, etc Current and voltage data sampling, etc.

Working magnetic flux density of Fe based amorphous alloy core: 1.35t ~ 1.40t, 1.6T ~ 1.7t for silicon steel. The weight of iron-based amorphous alloy power frequency transformer is about 130% of that of silicon steel power frequency transformer. However, even if the weight is heavy, the loss of iron-based amorphous alloy for power frequency transformer with the same capacity is 70% ~ 80% lower than that of silicon steel. Considering the loss, the total evaluation price is 89% The ability of Fe based amorphous alloy to resist power waveform distortion is stronger than that of silicon steel.

Characteristics and application of nanocrystalline magnetic core: High permeability, nanocrystalline Fe73 5Cu1Nb3Si13. 5B9 alloy has high saturation magnetic induction. The material becomes brittle after heat treatment and is easy to be processed into alloy powder. Compared with the nanocrystalline magnetic core wound with strip, the magnetic permeability of the nanocrystalline magnetic core is still very low and the soft magnetic properties are unstable. At present, the urgent problems to be solved are as follows: 1. Effectively control the growth of nanocrystals during heat treatment; 2. Molding of magnetic particle core; 3 Effect of heat treatment specification on soft magnetic properties of magnetic particle core.
