ASEIN as a manufacturer of carbon brushes and
graphites has a very large range of products suitable
for every need on the market.
Asein is a Spanish
manufacturer of carbon brushes for power tools,
forklifts and other industrial purposes. Asein is based
in Barcelona since 1983 and they are currently exporting
to 30 countries all over the world. They are leading
Spanish market thanks to the quality and competitive
prices of their products.
This is the reason for which we trust the ASEIN
brushes.
A brush is a device which
conducts
current between stationary
wires and moving parts, most commonly in a rotating
shaft. Typical applications include
electric motors,
alternators and
electric generators.
For an electric motor or generator to function, the
coils of the
rotor must be connected to complete an electrical
circuit. To accomplish this, (copper
or
brass) 'slip
rings' are affixed to the
shaft, and
springs press
braided
copper
wire 'brushes' onto the rings which conduct the
current. Later, these copper wire brushes were replaced
with
carbon blocks; but these blocks are still called
brushes. As the brushes are slowly
abraded, they may have to be replaced, if this is
possible.
If the copper rings are split into parts with
"interlaced" connections, the arrangement is called a
commutator.
Metal fiber brushes are currently being developed
again. These brushes may have advantages over current
carbon brushes, but have not yet seen wide
implementation.
There are distinguished basically 3 types of carbon
brushes:
- brushes for
automotive applications:
DC current, voltage 12 - 48 Volts.
- brushes for "household" applications:
AC current, voltage 110 / 220 Volts
- brushes for industrial motors: both AC and DC
current of various Voltages.
