Nanocrystalline Cores-Its Uses and Applications

Nanocrystalline Cores-Its Uses and Applications

2022-08-02

Nanocrystalline cores are mainly used in choke coils and transformers, as they possess high permeability, high saturation, and meager power loss. Nanocrystalline bodies comprise a molten metal put into a thin ribbon-like shape and later cool down to get to its supplying form. The molten metal used in the composition of nanocrystalline cores is mainly an iron-based soft magnetic amorphous alloy.

You'll see nanocrystalline everywhere in daily life as they are used in EMC filters, switch-mode power supplies, frequency converters, solar inverters, etc. In this article, you'll receive all the information regarding cores composed of nanocrystalline materials.



Nanocrystalline Core Properties

Here are the top-tier properties of nanocrystalline materials.


· High Permeability

The most prominent feature of a nanocrystalline core is its high permeability. It gets aligned to the direction of the magnetic field and can be effortlessly magnetized. Moreover, they increase the generation of electric motive force in the conductor. The change in the current flow automatically leads to a decrease in the number of turns of the windings.


· High and Notable Frequency

As the nanocrystalline materials have a low ability to change shape during magnetism, they are perfect for high-frequency applications.


· High Saturation Induction

They efficiently minimize the size of the component. This ability makes it feasible to limit the size of their cores.


· They Possess a High Curie Temperature

Curie temperature is when the magnetic materials go under a sharp change in their properties. As the nanocrystalline materials have high curie temperatures, they can entirely function even at 120 degrees.


· Low Core Loss

When dealing with magnetism, materials tend to generate a lot of heat. Magnetic core loss often occurs when the magnetic flux is altered in the core. As the nanocrystalline cores have a low core loss, they possess less heat than other cores. Therefore, they are highly efficient in working with AC-designed motors.


· Exceptional Heat Stability

Nanocrystalline cores can produce meager heat while magnetizing. It serves as a great advantage to the core, as the more significant the heat stability, the greater the efficiency of the core is. Nanocrystalline cores have a low core loss with their exceptional heat stability.


· Low Coercivity

Magnetic materials must have a meager resistance to magnetic force. If the material has high coercivity, they don't get magnetized easily and consume a lot of time and power to get magnetized. Nanocrystalline cores have low coercivity, which makes it effortless to get magnetized.




Is Toroidal Core Composed of Nanocrystalline Materials?

Nanocrystalline cores have countless benefits. Therefore, they possess high usability in the electric world and play a critical role in the composition of toroidal cores.

Nanocrystalline Toroidal Cores are Manganese and Zinc based cores soft ferrite cores. The usual ferrite core functions differently from the toroidal cores because of its high magnetic efficiency, unmatched and top-tier. That being the case, toroidal cores are preferred extensively over standard ferrite cores.

They are available in different sizes based on their functional requirements. The most common sizes of toroidal cores are T1005, T0904, T2206, etc.


Why Are Nanocrystalline Toroidal Cores Used In Transformers?

Nanocrystalline toroidal cores are very suitable for transformers, especially current transformers. These are the reasons why most of the cores are nanocrystalline transformer cores.


· Very Less Volume

One of the most significant advantages of the nanocrystalline toroidal cores is their significantly less volume despite their efficient toroidal cores consuming much less space in the body of transformers. Compared to other lined cores, it is worth noting that toroidal cores consume 64% less space.


· Possess High Magnetic Field

Due to their closed-looped body, nanocrystalline toroidal cores have a high magnetic field. The magnetic lines are extensively found around the toroidal cores, which is why they have high magnetic inductance.


· Less Weight

The nanocrystalline transformer cores are very light in weight. It is due to their less volume and compact ring-shaped body. The toroidal cores are mostly closely wounded, which is a notable factor in their low weight. They tend to have 50% less weight than other standard cores.


· An Easy Escape Of Magnetic Flux

The nanocrystalline toroidal cores have a round-shaped body, so it is feasible for magnetic flux to escape from its body. It makes them perfect for any environment as they radiate less electromagnetic interference.



Prime Applications That Use Nanocrystalline Cores in their Construction

Due to the efficient properties and functionality of the nanocrystalline cores, they are widely used in power applications. Here are some applications that use nanocrystalline cores in their construction.


· Power Transformer

We cannot recall transformers without their nanocrystalline transformer cores. Nanocrystalline cores have high permeability and heat stability, making them perfect for transformers. The transformers require cores that can magnetize quickly and promote low coercivity. The nanocrystalline cores effortlessly magnetize and, at the same time, have a low rate of core loss in case of high heat generation.


· EMC Filters

EMC filters are widely used in segregated areas of circuitry. They promote less to no interference in machinery, so they require nanocrystalline cores to do the job. The nanocrystalline cores have a small, compact, round-shaped body, wired in tight turns. This prevents any interference from the external environment. At the same time, small magnetic fluxes can escape from the body to cool the body of the core and avoid core loss.


· Inverters

You might have seen inverters in an average household. They do a significant job of converting direct current (DC) to an alternating current (AC). Due to the high permeability and heat stability, nanocrystalline cores are ideal for inverter cores. They easily magnetize and entirely function even at 120 degrees of temperature.


Where To Buy Nanocrystalline Cores?

Nanocrystalline cores are extensively used in electrical charging stations. There are available in every electric marketplace. However, most brands fail to give the outstanding quality and durability of the nanocrystalline cores. That’s not the case with Transmart. They have a wide range of nanocrystalline cores, including EMC nanocrystalline cores, nanocrystalline split cores, etc.

You can stay assured by the quality of the material they deliver, as they've been providing these services for years now. So, make your machinery highly efficient and effective by adding Transmart’s nanocrystalline cores to them.
