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.
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.
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.
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. See many more info on https://www.transmartcore.com/.
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.
