We know that the actual transformer always works in AC state, and the power loss is not only on the resistance of the coil, but also in the iron core magnetized by alternating current. Usually, the power loss in the iron core is called “iron loss”. The iron loss is caused by two reasons, one is “hysteresis loss” and the other is “eddy current loss”. Hysteresis loss is the iron loss caused by the hysteresis phenomenon in the magnetization process of the iron core. The size of this loss is directly proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of transformer core made of silicon steel is small, which can greatly reduce its heating degree.
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.

However, at the same BM, the loss of Fe based amorphous alloy is smaller than that of 0.23mm thick 3% silicon steel. It is generally believed that the reason for low loss is the thin thickness and high resistivity of iron-based amorphous alloy strip. This is only one aspect. The main reason is that the iron-based amorphous alloy is amorphous, the atomic arrangement is random, there is no magnetocrystalline anisotropy caused by atomic directional arrangement, and there is no grain boundary causing local deformation and composition offset. Therefore, the energy barrier hindering domain wall motion and magnetic moment rotation is very small, with unprecedented soft magnetism, so it has high permeability, low coercivity and low loss.
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.
