  • What factors should be considered when selecting magnetic powder cores?

    1.Application Requirements: First and foremost, clarify the performance and characteristics needed for your application, such as operating frequency, magnetic field strength, temperature range, power requirements, etc.

    2.Permeability and Saturation Flux Density: Select a magnetic core with appropriate permeability and saturation flux density based on your application requirements. If high magnetic field strength is needed, opt for a core with high saturation flux density.

    3. Frequency Characteristics: If your application operates at high frequencies, choose a magnetic core with good frequency characteristics to ensure stable performance at those frequencies.

    4.Loss Characteristics: Depending on your application's power requirements, select a magnetic core with low loss characteristics to improve system efficiency.

    5.Temperature Characteristics: Consider the operating temperature range of your application and choose a magnetic core with suitable temperature characteristics to ensure it performs reliably under various environmental conditions.

  • What issues should we pay attention to when using magnetic powder cores?

    1.Temperature control: The performance of magnetic powder cores is usually affected by temperature, so attention needs to be paid to controlling the operating temperature to avoid exceeding its specified temperature range. Excessively high temperatures may cause the magnetic properties of the magnetic powder core to decrease or be damaged.

    2. Avoid mechanical shock: Magnetic powder cores are usually fragile and easily damaged by mechanical shock. Be careful during installation and use to avoid collision or falling.

    3. Moisture-proof and moisture-proof: Magnetic powder core is sensitive to humid environment. Long-term exposure to humid environment may cause its performance to decrease or cause corrosion. Therefore, try to avoid humid environments during storage and use, and take moisture-proof measures.

  • What factors mainly determine the loss of magnetic powder core?

    1. Eddy Current Losses: Eddy current losses are a major loss mechanism in magnetic powder cores, arising from the power dissipation associated with eddy currents induced by varying magnetic fields. These losses are closely related to the geometric shape, magnetic permeability, and operating frequency of the powder core.

    2. Hysteresis Losses: Hysteresis losses occur due to the energy dissipation during the magnetization and demagnetization processes of the magnetic powder core within a cyclic magnetic field. They depend on the hysteresis loop characteristics of the core material, as well as the frequency and amplitude of the magnetic field.

    3. Joule Heating Losses: Joule heating losses result from the resistance of the magnetic powder core material, leading to power dissipation. These losses are more pronounced at high frequencies, especially when the resistance of the powder core is relatively high.

  • What are the advantages of powder core?

    1. High magnetic permeability and low core loss improve the efficiency of magnetic devices;

    2. Excellent temperature stability ensures stable performance over a wide temperature range;

    3. High saturation magnetic induction strength, suitable for high-performance applications.

  • What is the difference between powder core and traditional core?

    Powder cores are composed of fine magnetic particles bound together, offering low core losses and good high-frequency performance, making them ideal for applications like transformers and inductors. Traditional cores, made from homogeneous solid materials, are versatile but may have higher core losses and are more suited to lower frequency applications such as power transformers and electric motors, where stability is crucial.
