Product introduction: Wound-type annular cut iron core
Application fields: Commonly used in electromagnetic components such as small and medium-sized transformers, mutual inductors, magnetic amplifiers and leakage protectors.
Core material: High permeability permalloy soft tape material, such as 1J85, has excellent performance, high magnetic permeability and low loss.
Product advantages: High efficiency and energy saving. Compared with stacked iron cores, the no-load loss of the wound core is reduced by 7%-10%, and the no-load current is reduced by 50%-75%.
Exquisite craftsmanship: fully automatic winding, smooth and tight, no shear waste, material utilization rate is nearly 100%, and production efficiency is 5-10 times higher than stacked iron cores.
Low noise and environmental protection: The integrated structure reduces noise by 5-10dB compared with stacked iron cores.
High degree of customization: To meet the diverse needs of customers, various specifications can be customized.
Process features: CNC wire cutting, precise opening size. The center line of the incision passes through the center of the inner circle. After annealing, the residual magnetism is less than 5GS (0~2000GS)
The winding notched core must be annealed after processing. The purpose of annealing is to eliminate the internal stress generated during processing, thereby reducing the residual magnetism of the core. After annealing treatment, the residual magnetism of the iron core can be reduced to less than 5 Gauss (in the range of 0~2000 Gauss), which significantly improves the magnetic properties and stability of the iron core. Low residual magnetism means that the magnetic core can better maintain its magnetic properties in practical applications, reduce hysteresis losses, and improve the efficiency of electromagnetic components.
The application of winding notched cores in electromagnetic components has significant advantages. Its precise processing technology, low residual magnetism and excellent mechanical properties make it an ideal choice for electromagnetic components such as small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors. These features not only improve the performance and reliability of electromagnetic components, but also extend their service life.
