FAQ

  • What are the performance parameters of amorphous cores?

    1. Saturated magnetic induction intensity (Bsat): Saturated magnetic induction intensity refers to the maximum value at which the magnetic induction intensity of a magnetic core material reaches saturation under the action of an external magnetic field. A higher saturation magnetic induction intensity means that the magnetic core material can store more magnetic energy and has a higher magnetic saturation ability.

    2. Coercivity (Hc): Coercivity refers to the external magnetic field strength required to reduce the magnetic induction intensity of a magnetic core material to zero under the action of demagnetization. A higher coercivity means that the magnetic core material has a higher anti-magnetization ability and can maintain stable magnetic properties under the action of an external magnetic field.

    3. Hysteresis loss (Pv): Hysteresis loss refers to the energy loss generated by magnetic core materials during magnetization and demagnetization processes. Lower hysteresis loss means that the magnetic core material has lower energy loss and can provide higher energy conversion efficiency.

  • What is the application of amorphous cores?

    1. Transformers and inductors: Amorphous cores are widely used in transformers and inductors. Its high saturation induction intensity and low hysteresis loss give it advantages in efficient energy conversion and electrical energy transmission. The low hysteresis loss of amorphous magnetic cores can reduce energy loss and improve system efficiency.

    2. Power electronics applications: Amorphous cores are also widely used in the field of power electronics, such as switch-mode power supplies, frequency converters, motor drivers, etc. Amorphous cores can provide efficient electrical energy conversion, while also having lower temperature rise and thermal dissipation, which helps to improve the stability and efficiency of the system.

    3. Sensors and detectors: Due to their high magnetic permeability and low hysteresis characteristics, amorphous cores are widely used in sensors and detectors. For example, used in magnetic sensors, current sensors, magnetic memory, and magnetic stripe read/write heads.

  • What are the differences between nanocrystalline cores and
    other soft magnetic materials?

    1. Preparation process: The preparation of nanocrystalline cores usually adopts special processes, such as rapid solidification, sol-gel, and heat treatment. The preparation process of traditional soft magnetic materials is relatively simple. The preparation process of nanocrystalline cores requires higher technical requirements and cost investment.

    2. Magnetic permeability( μ): Nanocrystalline cores typically have higher magnetic permeability, which means they can more effectively conduct and concentrate magnetic fields. In contrast, traditional soft magnetic materials have lower magnetic permeability. High magnetic permeability enables nanocrystalline cores to provide better performance in applications such as sensors and inductors.

    3. Magnetic saturation induction intensity (Bs): Nanocrystalline cores typically have higher magnetic saturation induction intensity, which means they can store more magnetic energy. In contrast, traditional soft magnetic materials have lower magnetic saturation induction intensity. This gives nanocrystalline cores advantages in efficient energy conversion and energy storage applications.

  • What are the advantages of nanocrystalline cores ?

    1. High saturation magnetic induction intensity: Nanocrystalline magnetic cores have a high saturation magnetic induction intensity, which means they can store more magnetic energy. This enables nanocrystalline magnetic cores to have higher efficiency and smaller volumes in energy storage and conversion applications.

    2. Low hysteresis loss: Nanocrystalline magnetic cores have low hysteresis loss, which means that the energy loss generated during magnetic field changes is relatively small. This means that in high-frequency applications, nanocrystalline magnetic cores can reduce energy loss and heat generation, and improve system efficiency and stability.

    3. High-temperature stability: Nanocrystalline magnetic cores have good high-temperature stability and can maintain their magnetic performance in high-temperature environments. This gives nanocrystalline magnetic cores advantages in high-temperature applications, such as high-temperature power electronic devices and automotive electrification.
