On the motor slip ring for industrial development

With the development of science and technology , the motor type and use more diverse working conditions , and thus require a variety of different grades of brushes to meet these requirements , it is also the type of brush as the motor industry development more and more. Capsule Slip Rings

DC motor and the motor can be divided into AC motors , DC motors rotation of the rotor , the need to coil
The position of the magnetic field in a constant and continuous switching current changes direction, so the coil to the DC motor
A commutator . Commutator by the brushes and commutator rings , carbon brush is a brush because of the rotor
( Centrifuge rotor) for rotation of the brush is always rubbing the commutator ring , and also at the moment of commutation
Spark ignition eclipse , so brush DC motor is in the wearing parts in order to improve the DC motor
Service life , operating stability and reducing noise of the DC motor and electromagnetic interference , brushless DC motor
Have gradually replaced the brush motor trend. General AC motors do not constant magnetic field , so no need to commutator
, There is no need to brush .

Collector ring is used for motor commutator or slip ring , as export and import current sliding contact body , its electrical conductivity , thermal conductivity and good lubricating properties , and has a certain mechanical strength and commutation sparks instinct. Almost all motors use brushes , which are important components of the motor . Widely used in a variety of AC and DC generators, synchronous motor , battery DC motor, crane motor slip ring, various types of welding machine and so on.

Then we use slip ring assembly in the process should pay attention to what the problem?

( A ) general design slip ring motor at an altitude of no more than 1000m, ambient air temperature does not exceed 40 ℃ to run the place . ( 2 ) slip ring motor voltage change in the additional within ± 5% when the fixed rate can be rated for continuous operation . If the voltage changes more than ± 5% , then shall be specified by the manufacturer or limit the load test results . ( 3 ) to the cooling air from the outside of the motor , in order to avoid moisture , after the shutdown , must be promptly stopped the supply of cooling air .
( 4 ) Check the spark is normal under the brush , the motor slip ring ( or steering ) have burns and wear.
( 5 ) Check the motor slip ring in operation for unusual noise and vibration , the stator and rotor are relative to the friction .
