    Product Detail

    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.

    Frequently Asked Questions

    What are the primary applications of the wound-type annular cut iron core?
    It is commonly used in electromagnetic components such as small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors.
    What materials are used for manufacturing these iron cores?
    These cores are made of high permeability permalloy soft tape materials, such as 1J85, which offer excellent performance, high magnetic permeability, and low loss.
    What are the efficiency advantages of wound cores compared to stacked iron cores?
    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%, resulting in high efficiency and energy savings.
    Why is the annealing process necessary for winding notched cores?
    Annealing eliminates internal stress generated during processing. This reduces the residual magnetism of the core to less than 5 Gauss (within a 0~2000 Gauss range), which significantly improves magnetic properties, stability, and reduces hysteresis losses.
