A brief discussion on "amorphous motor"

A brief discussion on
Today we’re going to talk about a very cool technology topic: amorphous motors. This research field has a history, and now it seems that amorphous motors are expected to become the main material for motor stator cores!
Amorphous alloy is also called "liquid metal" or "metallic glass". This new type of soft magnetic material mainly contains elements such as iron, silicon, and boron. The production of amorphous alloy is through rapid cooling technology, which can form an amorphous alloy thin strip with a thickness of about 0.03mm. This material has the advantages of low coercivity, high magnetic permeability and high resistivity, making it very suitable for power transmission in the medium and low frequency fields.
At present, amorphous alloys are mainly used in distribution transformers to replace traditional grain-oriented silicon steel. Compared with oriented silicon steel, amorphous alloy is more energy-saving and environmentally friendly, with a shorter manufacturing process and higher efficiency. Moreover, it is also a green material that is recyclable throughout its life cycle, which is both energy-saving and environmentally friendly.
Now, scientists are considering using amorphous alloys as motor stator core materials to manufacture amorphous motors. This is of particular concern in the new energy vehicle industry. Compared with traditional silicon steel sheets, amorphous alloys have high resistivity under high-frequency conditions, which can effectively reduce eddy current losses and thereby improve motor efficiency.
Research on amorphous motors has a long history. From the amorphous alloy stator core patent applied for by General Electric Company in the United States in 1978 to the various amorphous alloy motors developed by Hitachi in Japan, this field has experienced rapid development. Various institutions, including companies and universities, have conducted intensive research in this area.
However, although the prototype of the amorphous motor has been manufactured, mass production has not yet been achieved. The thin, brittle, and hard characteristics of amorphous alloy materials make traditional stamping processing methods difficult. However, with the continuous advancement of technology, we have reason to believe that amorphous motors will play a greater role in high-frequency motor applications in the future. Summary: Amorphous motors will become a revolutionary technology, leading us into a new era that is more energy-saving and efficient.
