A brief discussion on "amorphous motor"
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.
