The stacked cores is usually made of high magnetic permeability 1J85 material. This material is known for its high magnetic permeability and low residual magnetism, which gives the laminated iron core significant advantages in the application of various electromagnetic components.
1J85 material has the characteristics of low residual magnetism. Low residual magnetism means that the material can quickly return to a non-magnetic state during magnetization and demagnetization, thereby reducing hysteresis losses and improving the efficiency and stability of electromagnetic components. This characteristic is particularly important for applications that require frequent magnetization and demagnetization, such as leakage protectors.
The design of the stacked cores also takes into account the heat dissipation and mechanical strength of the electromagnetic components. The lamination design not only helps optimize the magnetic circuit, but also improves the heat dissipation performance of the core and prevents overheating. At the same time, precise processing and high-quality material selection give the core good mechanical strength and can withstand the mechanical stress and vibration that electromagnetic components may encounter during operation.

Frequently Asked Questions (FAQ)
What are stacked cores and where are they typically used?
Stacked cores are laminated electromagnetic structures made from high magnetic permeability materials. They are widely used in electronic equipment components such as transformers, small transformers, sensors, reactors, and chokes.
Why is 1J85 material preferred for stacked cores?
1J85 is a permalloy soft magnetic material known for its exceptionally high magnetic permeability and low residual magnetism. This allows components to achieve high efficiency, low loss, and stable performance during operation.
What is the benefit of low residual magnetism in these cores?
Low residual magnetism ensures that the material quickly returns to a non-magnetic state during magnetization and demagnetization cycles. This reduces hysteresis losses and is critical for applications like leakage protectors that require fast response times.
How does the lamination design improve performance?
The lamination design optimizes the magnetic circuit path, improves heat dissipation to prevent overheating, and increases the overall mechanical strength to withstand operational stress and vibrations.
Are custom specifications available for stacked cores?
Yes. We offer a high degree of customization to meet diverse customer needs. Various specifications can be custom-made using precision punch molds and welding or lamination riveting processes.
Under what conditions are the magnetic properties in the specification table measured?
All magnetic property values for materials like 1J79B and 1J85B listed in the specification table are measured under DC (Direct Current) state in compliance with the YB/T5251-2013 standard.
