What kind of material Carbon Brush wear resistance strong?
What kind of material Carbon Brush wear resistance? Carbon Brush is also called brush According to the brush production methods, divided into two categories: one is colored brushes, that is, metal graphite brush, the other is a black brush. Colored brushes, containing non-ferrous metals, mainly copper powder, silver powder, followed by lead powder, tin powder, lead oxide powder, the balance of the scale graphite powder. How much of the metal powder content depends on the technical requirements of the brush. Most of the brush material made of graphite, in order to increase the conductivity, there are made of copper-containing graphite, graphite has a good electrical conductivity, soft texture and wear.
A device that transfers energy or signals between a fixed part of a motor or generator or other rotating machine. It is usually made of pure carbon and coagulant. The exterior is usually a square, stuck on a metal bracket, inside There is a spring to press it on the shaft, the motor rotation, the power through the inverter delivery to the coil, because its main component is carbon, called Carbon Brush, it is easy to wear. Should be regularly replaced and cleaned up.
Carbon Brush is used to run you know? Carbon Brush is a DC motor or winding motor to the rotor conductive device, can only be passed through it to the rotor up, the role in the motor is to change the current direction of the DC motor and AC Motor, DC motor is to change the rotor of the conductive coil, thus changing the rotor pole. Thereby changing the movement of the motor. Because the Carbon Brush is relatively soft, and wear, smooth, not easy to play spark. Conductive performance Ye Hao, not easy to oxidation, deterioration, deformation. So it is generally used for conductive contact surface.
Most of the material is made of graphite, in order to increase the conductivity, there are made of copper-containing graphite, graphite has a good conductivity, soft texture and wear-resistant.
The motor is the short name of the motor, that is, the motor. Motor can be divided into DC motor and AC motor, DC motor due to the rotation of the rotor, according to the coil in the constant magnetic field changes in the direction of constantly changing the direction of the current, so the DC motor coil needs a commutator. Only commutator or slip ring inside the motor have a Carbon Brush, the ordinary AC asynchronous motor is a squirrel cage structure, no Carbon Brush.
Carbon Brush used before the need for what work? Carbon Brush for brush motor inside the top of the inverter surface, the motor rotation, the power through the inverter delivery to the coil, because its main component is carbon, known as the Carbon Brush It is easy to wear. Cangzhou Yongxin Carbon Brush manufacturers here to remind you that the new Carbon Brush before you need to do what?
New Carbon Brush before use need to do the work of four points:
1, the new Carbon Brush must be used before the grinding (grinding), to ensure that the Carbon Brush and slip ring surface contact up to 80%, Carbon Brush into the brush to ensure that the upper and lower free to move, if the card astringent phenomenon should be Will be four sides of the Carbon Brush with sandpaper to keep the Carbon Brush and brush the gap between the wall should be between 0.1-0.3 mm, so as not to brush the card in the brush or because of the gap is too large to produce swing. Brush the lower edge of the distance from the slip ring surface should be maintained at about 3mm ~ 4mm mm.
2, at the same time, each brush holder only for 1 to 2 Carbon Brush, and the old and new Carbon Brush models must be consistent.
3, regularly with a DC clamp meter to measure the current sharing of the Carbon Brush evenly.
4, with a spring scale to check the pressure of the Carbon Brush should be uniform and stable, the unit pressure is usually between 1.1kg ~ 2.5kg, the Carbon Brush between the uneven pressure difference of less than 5%.
