With the development of automotive industry towards new energy and intelligence, compared to the traditional mechanically oriented drive method, electric drive becomes the main drive mode of new energy vehicles. Therefore, the challenge for the development of new energy vehicles lies in the “Three electric systems”, i.e., battery, electric drive and electric control. A large number of magnetic materials and devices are involved.

Smart meter is an advanced metering device based on modern communication technology, computer technology and measurement technology to collect, analyze and manage electric energy information data. The composition and working principle of electronic smart meters are different from traditional inductive energy meters.

Amorphous core is a magnetic core made of an amorphous metallic materials, it has high magnetic permeability, low hysteresis loop and low iron loss. The manufacturing process of amorphous core includes solidification quickly, ball milling into powder, fill molding, heat treatment. Manufactured amorphous cores have a homogeneous organization structure and high permeability.

Among power transformers, amorphous alloy transformers are very different from ordinary transformers. Below, we’ll explore these differences, as well as the pros and cons of amorphous alloy transformers.

Amorphous Ribbon is a new soft magnetic material. It is produced through the advanced technology of rapid solidification of molten metal at a cooling rate of about a million ℃/sec. During this process the metal is rapidly quenched as a form of ribbon with 25-35 μm thickness, and the micro-structure of the alloy is the amorphous due to the high quenching rate.

The best core for an inductor depends on the specific application.
