Custom Winding Notched Core from China Suppliers - High Permeability Permalloy Wound Core Factory
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 & Eco-Friendly
The integrated structure reduces noise by 5-10dB compared with stacked iron cores.
High 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.

It is commonly used in electromagnetic components such as small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors.
They are made from high permeability permalloy soft tape materials, such as 1J85, which deliver excellent performance, high magnetic permeability, and low loss.
Wound cores are highly efficient and energy-saving. Compared with stacked iron cores, the no-load loss is reduced by 7%-10%, the no-load current is reduced by 50%-75%, and noise is reduced by 5-10dB.
Annealing eliminates the internal stress generated during processing, which reduces the residual magnetism of the core to less than 5 Gauss (in the 0~2000 Gauss range). This significantly improves magnetic properties, stability, and efficiency while reducing hysteresis losses.
The cores feature CNC wire cutting, ensuring a precise opening size where the center line of the incision passes directly through the center of the inner circle.
Yes, various specifications can be customized to meet the diverse and specific requirements of customers.
