As the name suggests is used to electrically conductive slip ring slip
ring slip ring series in all the most widely used , also known as brushless slip ring
, carbon brushes, slip ring, slip ring , slip ring , rotary pass,
rotating electrical joints, dedicated to the unlimited continuous
rotation , the transmission power of power, signal power .
The
choice of the motor brush commutation sparks have an important role in
inhibition , should be power, voltage , load characteristics and the
selection conditions such as the peripheral speed commutator . Commonly
used electric graphite brushes , because resistance coefficient and
contact voltage higher, suppression spark favor. But for low-voltage
motors , the excessive contact voltage to make it in the proportion of
the total voltage drop is too large, so the use of metal graphite
brushes .
Since the majority of structural defects brush , so researchers developed a second generation of electricity on the Capsule Slip Rings
, slip ring to avoid the kind of brush structure of many shortcomings,
such as easy to wear , not oxidation . As modern technology advances,
brush slip ring technology has become increasingly sophisticated , just
before the use of copper and copper ring brush contacts for signal and
current transmission, relatively soft due to copper , rotation speed or
when the use of time after a long , easily deformed , affecting close
contact , thus resulting in distortion of current and signal
transmission . Behind the development of precious metal brushes and
copper rings to solve this problem , such as adding trace elements of
the alloy conductive materials, rare earth metals, rare metals , etc., a
good solution to this problem . Now, brush slip ring slip ring is still
the main force of cost . Many large amount of manufacturers, both in
the use of cost-effective electrical slip ring , especially equipment
price is not high, the number of very large companies , due to cost
reasons, brush slip ring is still their first choice.
