The carbon brush of the wound weapon used on the motor often has several batches of buckles. Why does the wound carbon brush on the motor emit sparks:
When we use the carbon brush of the wound motor, due to the continuous wear of the carbon brush during the long-term operation, the uneven contact surface, the pressure of the carbon brush may not be the unround collector ring and the oil droplets or other debris on the bearing falling between the collector ring and the carbon brush, etc., which will all form sparks from the carbon brush of the electric tool.
How to eliminate sparks from the carbon brush of electric tools: we can use fine sandpaper to polish the contact surface of the carbon brush and the collector ring smoother, perhaps adjust the pressure of the carbon brush appropriately, and check whether the collector ring is round or not. we should also use clean cotton yarn, dip a little gasoline on it to wipe the collector ring and the carbon brush clean, and then eliminate the oil stain on the bearing and the carbon brush, do a good job of collecting ring and carbon brush protection methods, can be useful to reduce the probability of winding click power tool carbon brush spark. Carbon brushes are usually made of pure carbon and coagulant. The appearance is usually square and stuck on a metal bracket. There is a spring inside to press it tightly on the rotating shaft. For example, if the oil drilling is completed and the dike fee is required for inspection, the instrument must be placed down, that is, the signal must be rotated through the carbon brush (the outer package steel is the instrument I said to a mortal. Carbon brushes are divided into calming heating luminous strips, with wires leading out at the top. The volume is large and small. As a kind of sliding, carbon brush can not be widely used in electrical.
The primary material of carbon brush
Product materials are primarily electrochemical graphite, impregnated graphite, metal (copper, silver) graphite.
