Best transformer core manufacturer and supplier in China? Nanocrystalline core is getting more and more popular in the electronic and electrical industries, for its high electrical performances. Our features nanocrystalline core material products are Nanocrystalline Common mode choke cores and Nanocrystalline Current Transformer cores. See extra details on magnetic core manufacturers. Soft magnetic materials are those materials that are easily magnetised and demagnetised. They typically have intrinsic coercivity less than 1000 Am-1. They are used primarily to enhance and/or channel the flux produced by an electric current. The main parameter, often used as a figure of merit for soft magnetic materials, is the relative permeability (µr, where µr = B/ µoH), which is a measure of how readily the material responds to the applied magnetic field. The other main parameters of interest are the coercivity, the saturation magnetisation and the electrical conductivity.
Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel with silicon (silicon is also called silicon), and its silicon content is 0.8 ~ 4.8%. The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can produce large magnetic induction intensity, which can reduce the volume of transformer.
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.

Now, the test of magnetic core material loss of power frequency power transformer is carried out under sine wave voltage with distortion less than 2%. The actual power frequency power grid distortion is 5%. In this case, the loss of iron-based amorphous alloy increases to 106% and that of silicon steel increases to 123%. If the high-order harmonic is large and the distortion is 75% (such as power frequency rectifier transformer), the loss of iron-based amorphous alloy increases to 160% and the loss of silicon steel increases to more than 300%.
After surface insulation treatment, the magnetic core is evenly mixed with the binder, pressed and annealed. There are basically three ways to obtain nanocrystalline powder: amorphous strip crushing after annealing and crystallization, mechanical alloying and molten alloy atomization. At present, mechanical alloying is still in the laboratory research stage. A few companies produce amorphous strip crystallization in small quantities in China, but it is unable to expand the market due to cost reasons. Compared with other methods, molten alloy atomization method has high efficiency and low cost. Its disadvantage is that the amorphous content of the powder is low and the loss is high.
