Leave a message
Nanocrystalline runway cores are primarily used as magnetic cores in transformers to improve their efficiency and performance. Their unique structure provides high magnetic permeability, which increases accuracy, reduces volume, and improves linearity in current transformers, making them suitable for applications like current sensing and noise absorption in various power electronics.
Nanocrystalline runway core Key applications
Current transformers: Nanocrystalline cores are used in current transformers to increase accuracy and reduce their physical size. This is due to the high permeability and saturation inductance of the core material.
Noise absorption: They are used as inductive absorbers to mitigate high-frequency noise in systems like inverter-motor setups, converting electrical noise into thermal energy to protect components like motor bearings.
Power electronics: The high performance of these cores makes them suitable for a range of power electronics applications that require accurate current measurements and efficient power conversion.
High-frequency transformers: They are utilized in high-frequency transformers and filters due to their excellent magnetic properties at high frequencies.
Other electrical components: While transformers are a primary application, the benefits of nanocrystalline cores can be applied to other electrical components that require high-efficiency magnetic cores, such as common-mode chokes.
When to choose which core material
Choose nanocrystalline cores when you need high power density, high efficiency, and compact size for high-frequency applications (e.g., 10 kHz to 100 kHz).
Choose amorphous cores when cost is a significant factor and the application operates at lower frequencies or requires high mechanical strength.
Choose ferrite cores for low-frequency applications where their moderate performance is acceptable.
Choose silicon iron cores for low-frequency power applications where their high saturation flux density is suitable and high-frequency losses are not a concern.
