What problems will occur if the carbon brush is broken?
2 Answers
Carbon brush damage can lead to sparking and burning of the commutator. Here are specific details about carbon brushes: 1. Identification methods: The brush overheats during operation, produces loud noise, or is damaged. There is significant sparking during brush operation. The contact area between the carbon brush and slip ring is less than 70%. The brush spring pressure is inappropriate, etc. 2. Impact: If not replaced in time, it can damage the rotor's copper sheets, cause poor contact during operation, negatively affect the coil, and reduce machine power. The machine will overheat, reducing its service life. Carbon brushes are devices that transfer energy or signals between the stationary and rotating parts of motors, generators, or other rotating machinery. When the motor rotates, they deliver electrical energy to the coil through the commutator.
Last time my car wouldn't start, there was no response when turning the key. It turned out the carbon brushes were worn out. These components are inside the starter motor - when they wear down, electricity can't pass through, leaving the entire vehicle paralyzed with the engine unable to turn over. I've also experienced it affecting the alternator, causing the battery light to flicker and preventing proper charging. If left unrepaired, it can burn out the motor coils, sending repair costs skyrocketing. Regular inspections are crucial, especially for older vehicles over a decade old where carbon brushes have shorter lifespans. Replacing them every 2-3 years can prevent major issues. If a failure occurs, don't panic - call a tow truck immediately and get it to the shop. Safety comes first.
