    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, featuring excellent performance, high magnetic permeability, and low loss.

    Product Advantages

    High efficiency and energy saving. Compared with stacked iron cores, no-load loss is reduced by 7%-10%, and no-load current is reduced by 50%-75%.

    Exquisite Craftsmanship

    Fully automatic winding, smooth and tight, zero shear waste, material utilization rate near 100%. Production efficiency is 5-10 times higher than stacked iron cores.

    Low Noise & Eco-Friendly

    The integrated structure reduces vibration and noise by 5-10dB compared with traditional stacked iron cores.

    High Customization

    To meet the diverse needs of customers, various custom specifications and sizes can be tailored and manufactured.

    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 (FAQ)

    What is a wound-type annular cut iron core?
    It is a highly efficient electromagnetic core wound from high-permeability soft magnetic materials (like permalloy 1J85) and cut with high-precision CNC wire cutting to meet specialized transformer and inductor requirements.
    Why must the winding notched core be annealed?
    Annealing eliminates the internal physical stress generated during processing. This process reduces the residual magnetism of the iron core to less than 5 Gauss, which significantly improves the core's magnetic stability and reduces hysteresis losses.
    What are the main advantages of wound cores compared to stacked cores?
    Compared to traditional stacked iron cores, wound cores offer a 7%-10% reduction in no-load loss, a 50%-75% reduction in no-load current, and lower operation noise by 5-10dB due to their integrated design.
    What core materials are used for these iron cores?
    They are made of high-permeability permalloy soft tape materials, such as 1J79B and 1J85B, which exhibit excellent magnetic properties, low coercivity, and high saturation magnetic induction.
    Are custom sizes and specifications available?
    Yes, we offer a high degree of customization. Various specifications, strip thicknesses (such as 0.05mm to 0.3mm), and dimensions can be customized to meet specific application requirements.
    What are the main application fields for these cores?
    They are widely used in electromagnetic components, including small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors.
