Brush looks a bit like a pencil eraser to rub strips, as on top of a wire leads. Volume sizes. Brush as a sliding contact member, has been widely used in many electrical devices. Main products are made of graphite electric Baptist grease graphite, metals (copper, silver) graphite. The role of the carbon brush brush motor inside the top surface of the commutation, motor rotation when electrical energy is transported through the commutation to the coil, as its main ingredient is carbon, known as carbon brushes, it is easy to wear. Regular maintenance should be replaced, and clean carbon deposits. Brush Brush type of resin type, electrical classes, and non-ferrous metals, which due to the use of different materials and processes on different motors. Brush test methods for the protection of the normal operation of the motor, brushless type the correct choice is very important, due to the different manufacturing brushes selected raw materials and process, its technical performance are also differences. Therefore, the choice of brushes, brushes should be taken into account for the performance and motor brushes requirements. Brush should be a good indicator of performance: a commutator or collector ring surface can quickly form a layer of uniform, moderate and stable oxide film. 2 Brush long life and does not wear commutator or collector ring 3 carbon brush commutation and has good current collecting performance, the spark suppressed within the allowable range, and the energy loss is small. Brush four runs, but the heat, noise, assembly and reliable, is not damaged. 1. The correct installation method within Brush Brush Brush Holder to ensure that load can move freely up and down, brushes and brush holder gap between the inner wall of 0.1-0.3 mm, in order to avoid being carbon brushes and brush holder because the gap is too produce large swings. Brush Woxia distance from the edge of the commutator surface should be maintained at about 2 mm. If the distance is too small, easy to be injured commutator brush holder, the distance is too large, brushes easily fibrillation caused damage. 2. On the same motor, in principle, should use the same type of brush, but it is particularly difficult for the individual to change to medium-sized motor, can be twin brush, slide it into the side of using good lubricating properties, the use of curb side slide Sparks ability of carbon brushes, carbon brush run so improved. 3. The same applied to the various brushless motor unit pressure should seek uniform current distribution in order to avoid uneven, leading to overheating and sparks individual brushes. Unit pressure carbon brushes should be "brushes technical performance table" to choose for high speed motors or motors working under vibration conditions, should increase pressure units, one guaranteed to work. Analogy: Traction machine motor brushes pressure 0.4-0.6kgf / cm2. Typically Brush pressure is too high, is increasing carbon brush wear, the unit pressure is too small, the contact is unstable, prone to mechanical sparks.

For large units, down to replace carbon brushes, is bound to affect the production, you can choose not stop, we usually advise clients to practice every 20% of the carbon brushes replacement (ie, 20% of stems per each motor), every interval of 1-2 weeks until the rest of the run and then gradually replace the carbon brushes in order to ensure continuous operation of the unit normal. 2. In order to make good contact with the commutator brushes, new brushes should be grinding radians, radians general wear on the motor. Place a glass of fine sandpaper between brushes and commutator, in the normal spring pressure along the direction of rotation of the grinding motor brushes, sandpaper should try to stick tight commutator, brushes arc until the match, then remove sandpaper, using compressed air to blow the dust, then wipe clean with a soft cloth. Emery paper abrasive brushes should not be used to prevent the diamond particles are embedded in the commutator slots, the motor is running, brushes and commutator surface abrasions. After grinding arc, the first 20-30% of the motor load operation hours, so that the carbon brushes and commutator running, and to establish uniform oxide film. And then gradually increase the current to the rated load.
