Conventional Type Single Phase Distribution Transformer with Amorphous Metal Core

Oct 23, 2025

Leave a message

An amorphous metal core is a magnetic core made from a rapidly cooled, glass-like alloy with a disordered atomic structure, unlike the crystalline structure of conventional silicon steel. This structure results in lower core losses, higher efficiency, and smaller, lighter designs in applications like transformers and inductors. Amorphous metal cores are particularly beneficial at high frequencies where they outperform silicon steel.

Conventional Type Single Phase Distribution Transformer with Amorphous Metal Core

Manufacturing:

Molten metal alloy is cooled extremely quickly to prevent it from forming a crystalline structure, instead solidifying into a thin ribbon.

Atomic structure:

The resulting material has an atomic structure similar to glass, with no repeating crystalline pattern.

Magnetic properties:

This lack of a crystalline structure means there is no magnetic crystalline anisotropy, resulting in high magnetic permeability and significantly lower energy losses.

amorphous metal core Key advantages

Reduced no-load losses:

Amorphous metal cores can reduce no-load losses by up to 70% compared to traditional silicon steel, leading to significant energy savings.

Higher efficiency:

They offer superior energy efficiency, especially in applications like distribution transformers, which helps lower utility bills and reduce carbon emissions.

Improved performance at high frequencies:

Amorphous cores perform better at higher frequencies than silicon steel, which experiences high eddy current and hysteresis losses at these frequencies.

Smaller and lighter designs:

Their superior magnetic properties allow for smaller and more efficient designs in high-frequency applications like inverters and power supplies.

amorphous core applications

Electric grid distribution transformers
Power factor correction (PFC) boost inductors
Adjustable speed drives (ASDs)
Switch-mode power supplies (SMPS)
Common mode chokes
Rail transit systems
