    Product Detail

    Product Overview

    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).

    Detailed Description
    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 are the primary application fields for 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 to manufacture these iron cores?

    The iron cores are made from high permeability permalloy soft tape materials, such as 1J85, which offer excellent magnetic properties and low loss.

    How does the wound core improve energy efficiency compared to stacked cores?

    Compared with stacked iron cores, the wound core reduces no-load loss by 7%-10% and reduces no-load current by 50%-75%, resulting in higher efficiency and energy savings.

    Why is annealing required after processing the winding notched core?
