Today we're going to talk about a really cool technical topic: amorphous motors. This field of research has been around for some time, and now it seems that amorphous motors are expected to be the main material for stator cores of motors
Amorphous alloys, also known as "liquid metals" or "metallic glasses", are new soft magnetic materials that mainly contain elements such as iron, silicon, and boron. The production of amorphous alloys is carried out by rapid cooling technology, which can form a thickness of about 003mm amorphous alloy thin strip. This material has the advantages of low coercivity, high permeability and high resistivity, which makes it ideal for power transmission in the low and medium frequency range.
At present, amorphous alloys are mainly used in distribution transformers to replace traditional oriented silicon steel. Compared with oriented silicon steel, amorphous alloys are more energy-efficient and environmentally friendly, with a shorter manufacturing process and higher efficiency. Moreover, it is also a green material that can be recycled throughout the life cycle, which is both energy-saving and environmentally friendly.
Now, scientists are considering using amorphous alloys as stator core materials for motors to make amorphous motors. This is of particular interest 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 improve motor efficiency.
The study of amorphous motors has a long history. From the patent of amorphous alloy stator core applied by General Electric Company of the United States in 1978 to a variety of amorphous alloy motors developed by Hitachi Company of Japan, this field has experienced rapid development. Various institutions, including companies and universities, have conducted in-depth research in this area.
However, although the prototype of the amorphous motor has been manufactured, it has not yet achieved mass production. The thin, brittle, and hard nature of amorphous alloy materials makes traditional stamping difficult. However, with the continuous progress of technology, we have reason to believe that amorphous motors will play a greater role in high-frequency motor applications in the future.
Bottom line: Amorphous motors will be a revolutionary technology that will lead us into a new era of greater energy efficiency.
