Magnetic core manufacturer by Transmart? 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. Discover even more details on toroidal transformer core. 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.
The transformer is made according to the principle of electromagnetic induction Two windings, a primary winding and a secondary winding, are wound around the closed iron core column When AC power supply voltage is applied to the primary winding There is alternating current in the original Rao group, and the magnetic potential is established. Under the action of the magnetic potential, the alternating main flux is generated in the iron core. The main flux passes through the iron core at the same time, AC link the primary and secondary windings are closed, and the induced electromotive force is generated in the primary and secondary windings respectively due to the action of electromagnetic induction.
As the iron core of the transformer, generally, 0.35mm thick cold rolled silicon steel sheet is selected. It is cut into long pieces according to the size of the required iron core, and then overlapped into “day” shape or “mouth” shape. In principle, in order to reduce eddy current, the thinner the silicon steel sheet, the narrower the spliced strip, and the better the effect. This not only reduces the eddy current loss and temperature rise, but also saves the material of silicon steel sheet. But in fact, when making silicon steel sheet iron core. Not only from the above favorable factors, because making the iron core in that way will greatly increase the working hours and reduce the effective section of the iron core. Therefore, when making transformer iron core with silicon steel sheet, we should start from the specific situation, weigh the advantages and disadvantages and choose the best size.

It is worth noting that Japan is vigorously developing FEMB amorphous alloy and nanocrystalline alloy. Its BS can reach 1.7 ~ 1.8T, and the loss is less than 50% of the existing FeSiB Amorphous Alloy. If it is used in power frequency electronic transformer, the working magnetic flux density can reach more than 1.5T, while the loss is only 10% ~ 15% of silicon steel power frequency transformer, it will be a more powerful competitor of silicon steel power frequency transformer. Japan is expected to successfully trial produce FEMB amorphous alloy power frequency transformer and put it into production in 2005.
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.
