Top 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 additional information at 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.
As for why it can boost and depressurize It needs to be explained by Lenz’s law The magnetic flux generated by the induced current always hinders the change of the original magnetic flux. When the original magnetic flux increases, the magnetic flux generated by the induced current is opposite to the original magnetic flux. In other words, the induced flux generated by the secondary winding is opposite to the main flux generated by the original winding, so the secondary winding has a low-level alternating voltage. So The iron core is the magnetic circuit part of the transformer The winding is the circuit part of the transformer.
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. 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.
Silicon steel is a traditional magnetic material mainly for 50Hz to 1000Hz electronic and electrical applications. The toroidal core is one of the main products of Transmart Industrial. Our silicon steel core series has many styles to meet the diversified needs of customers. We manufacture various type of cores in silicon steels, such as Current Sensor Cores, silicon steel transformer core, Instrument Transformer Cores, Torodal cores, C-cores, Unicore etc. Transmart Industrial carries out strict quality monitoring and cost control on each production link of toroidal core, from raw material purchase, production and processing and finished product delivery to packaging and transportation. This effectively ensures the product has better quality and more favorable price than other products in the industry. Find more details at https://www.transmart.net/.
The annealing temperature of iron-based amorphous alloy is lower than that of silicon steel, and the energy consumption is small, and the iron-based amorphous alloy magnetic core is generally manufactured by special manufacturers. Silicon steel magnetic cores are generally manufactured by transformer manufacturers. According to the above comparison, as long as it reaches a certain production scale, iron-based amorphous alloy will replace some silicon steel markets in electronic transformers within the power frequency range. In the medium frequency range of 400Hz to 10kHz, even if new silicon steel varieties appear, iron-based amorphous alloy will still replace most silicon steel markets with a thickness of less than 0.15mm.
At present, up powder core occupies the main share in the high-end market. However, due to the complex manufacturing process of M, that is, powder core and the noble price of raw materials, the price of powder core remains high and the scope of application is restricted to a certain extent. In recent years, iron-based nanocrystalline soft magnetic powder core has attracted much attention because of its low price, simple preparation process and excellent performance. Its research is quite active, which is expected to replace the local use of up powder core and be applied in the field of high frequency.
