Excellent amorphous cores manufacturer and supplier: Transmart is a transformer core manufacturer with years of experience, mainly providing nanocrystalline cores, amorphous cores, silicon steel cores, common mode chokes, etc. We specialized in a broad range of tape wound cores in amorphous metal materials, nanocrystalline alloys, silicon electrical steels, and mu metal nickel alloys for a wide variety of applications including solar inverters, home appliance, audio system, etc. Nanocrystalline Ribbons are thin strips of material that have been engineered at the nanoscale to possess unique properties and characteristics. These ribbons are typically made up of highly ordered crystalline structures with grain sizes on the order of a few nanometers, giving them exceptional strength and durability.

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.
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%.

Leakage protection, relay protection, servo motor protection, fire monitoring, etc Current and voltage data sampling, etc. Read many more details at transmartcore.com.
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.
