Top rated nanocrystalline
transformer core supplier with Transmart? Nanocrystalline core is getting
more and more popular in the electronic and electrical industries, for its high
electrical performances. Our features nanocrystalline core material products
are Nanocrystalline Common mode choke cores and Nanocrystalline Current
Transformer cores. Soft magnetic materials are those materials that are easily
magnetised and demagnetised. They typically have intrinsic coercivity less than
1000 Am-1. They are used primarily to enhance and/or channel the flux produced
by an electric current. The main parameter, often used as a figure of merit for
soft magnetic materials, is the relative permeability (µr, where µr = B/ µoH),
which is a measure of how readily the material responds to the applied magnetic
field. The other main parameters of interest are the coercivity, the saturation
magnetisation and the electrical conductivity.
As for why it can boost and depressurize It needs to be
explained by Lenz’s law The magnetic flux generated by the induced current
always hinders the change of the original magnetic flux. When the original
magnetic flux increases, the magnetic flux generated by the induced current is
opposite to the original magnetic flux. In other words, the induced flux
generated by the secondary winding is opposite to the main flux generated by
the original winding, so the secondary winding has a low-level alternating
voltage. So The iron core is the magnetic circuit part of the transformer The
winding is the circuit part of the transformer.
This is because the sheet iron core can reduce another
iron loss – “eddy current loss”. When the transformer works, there is
alternating current in the coil, and the magnetic flux generated by it is of
course alternating. This changing magnetic flux produces an induced current in
the iron core. The induced current generated in the iron core flows in a ring
in a plane perpendicular to the magnetic flux direction, so it is called eddy
current. Eddy current losses also heat the core. In order to reduce the eddy
current loss, the iron core of the transformer is stacked with silicon steel
sheets insulated from each other, so that the eddy current passes through a
small section in the narrow and long circuit, so as to increase the resistance
on the eddy current path; At the same time, the silicon in silicon steel
increases the resistivity of the material and reduces the eddy current. rolled
silicon steel sheet is selected. It is cut into long pieces according to the
size of the required iron core, and then overlapped into “day” shape or “mouth”
shape. In principle, in order to reduce eddy current, the thinner the silicon
steel sheet, the narrower the spliced strip, and the better the effect. This
not only reduces the eddy current loss and temperature rise, but also saves the
material of silicon steel sheet. But in fact, when making silicon steel sheet
iron core. Not only from the above favorable factors, because making the iron
core in that way will greatly increase the working hours and reduce the
effective section of the iron core. Therefore, when making transformer iron
core with silicon steel sheet, we should start from the specific situation,
weigh the advantages and disadvantages and choose the best size.
Transmart amorphous core manufacturer & supplier is
mainly engaged in the production and sales of amorphous core materials. The
amorphous core transformer is one of Transmart Industrial’s multiple product
series.Transmart Industrial’s amorphous C-core is manufactured in strict
accordance with relevant national standards. Every detail matters in the
production. Strict cost control promotes the production of high-quality and
priced-low product. Such a amorphous transformer is up to customers’ needs for
a highly cost-effective product.
Amorphous nanocrystalline alloys are competing with soft
ferrite in the field of medium and high frequency. In 10kHz to 50KHz electronic
transformer, the working magnetic flux density of iron-based nanocrystalline
alloy can reach 0.5T and the loss P0.05 5 / 20K ≤ 25W / kg, so it has obvious
advantages in high-power electronic transformer. In 50 kHz to 100 kHz
electronic transformer, the loss of iron-based nanocrystalline alloy is P0.05 2
/ 100k is 30 ~ 75W / kg, Fe based amorphous alloy P0.05 2 / 100k is 30W / kg,
which can replace some ferrite markets.
Characteristics and application of nanocrystalline
magnetic core: High permeability, nanocrystalline Fe73 5Cu1Nb3Si13. 5B9 alloy
has high saturation magnetic induction. The material becomes brittle after heat
treatment and is easy to be processed into alloy powder. Compared with the
nanocrystalline magnetic core wound with strip, the magnetic permeability of
the nanocrystalline magnetic core is still very low and the soft magnetic
properties are unstable. At present, the urgent problems to be solved are as
follows: 1. Effectively control the growth of nanocrystals during heat
treatment; 2. Molding of magnetic particle core; 3 Effect of heat treatment
specification on soft magnetic properties of magnetic particle core.
