A Nanocrystalline Core is a material composed of nanoscale grains commonly used in electromagnetic devices such as transformers and inductors. Compared with traditional ferromagnetic materials, nanocrystal materials have higher permeability and lower loss, which can perform well in high-frequency applications.

Characteristics of nanocrystal core:
High permeability: The microstructure of nanocrystal materials enables them to achieve high permeability at lower magnetic fields.
Low energy loss: Due to its fine grain, the nanocrystal core produces low eddy current losses in alternating magnetic fields, which is suitable for high-frequency applications.
Excellent temperature stability: nanocrystal materials can still maintain good magnetic properties at high temperatures.
The role of steel shell:
Steel shells are often used to protect the nanocrystal core, providing mechanical strength and structural stability. The steel case can also help shield from external electromagnetic interference and enhance the overall performance of the device.

Application field:
Transformers: Used for high performance transformers, especially in high frequency and high power applications.
Inductors: In power management and filters, nanocrystal cores can improve efficiency and performance.
Motors and generators: Improve the efficiency of motors and generators and reduce energy loss.
This combined design makes the combination of the nanocrystal core and the steel shell more and more important in modern electrical engineering, especially in the pursuit of high efficiency and miniaturization of equipment.
