Amorphous cutting core C core

Amorphous C-core is the preferred solution for high frequency and low loss applications such as uninterruptible power supply (UPS), SMPS power factor correction (PFC) inductor, filter inductor, and high frequency transformer and inductor. Compared with ferrite core, amorphous core has a wider operating temperature range, significantly larger magnetic flux and significantly higher high-frequency impedance. The amorphous notch magnetic core can also withstand the high pressure brought by tension without fracture or corrosion.

Amorphous magnetic cores allow smaller, lighter and more energy efficient designs in many high frequency applications for Invertors, UPS, ASD (Adjustable speed drives), and Power supplies (SMPS). Amorphous metals are produced in using a rapid solidification technology where molten metal is cast into thin solid ribbons by cooling at a rate of one million°C/second. Amorphous magnetic metal has high permeability due to no crystalline magnetic anisotropy.Amorphous Alloys are metallic glass materials without a crystalline structure. Amorphous-Alloy Cores provide better electrical conductivity, higher permeability and magnetic density, and efficient operation over a wider temperature range than cores made from conventional materials. Smaller, lighter, and more energy-efficient designs are possible for transformers, inductors, invertors, motors, and any device requiring high frequency, low loss performance. Typical Applications:
  • Transformers for electric grid power and distribution
  • Current transformers
  • High frequency, energy storage inductors
  • Saturable cores
  • Motors
  • Invertors
  • High-frequency electronic devices
  • GFCI’s (Ground Fault Circuit Interrupters)

Advantages of using amorphous cores:

  • High permeability
  • High magnetic density
  • Reduced distribution and core losses
  • Wide range of frequency properties
  • Low coercivity forces
  • Low no-load loss
  • Low temperature rise
  • Affordably priced
  • Excellent resistance to corrosion
  • High harmonic wave tolerances
Craftsmanship Amorphous alloys are formed by adding a certain amount of glass forming agent to the molten metal, and rapidly quenching and casting using a narrow ceramic nozzle under high temperature melting conditions. Amorphous alloys have the similar characteristics of glass structure, which not only make them have excellent mechanical properties, physical properties and chemical properties, but more importantly, the new technology of producing amorphous alloys using this rapid quenching method is less than the cold-rolled silicon steel sheet process. 6 to 8 processes can save energy consumption by 60% to 80%, which is an energy-saving, time-saving and efficient metallurgical method. Moreover, the amorphous alloy has low coercivity and high magnetic permeability, and its core loss is significantly lower than that of oriented cold-rolled silicon steel sheet, and its no-load loss can be reduced by about 75%. Therefore, the use of amorphous alloys instead of silicon steel sheets to manufacture transformer cores is one of the main means to save energy and reduce consumption in today’s power grid equipment.
