Commutator Sparking Of Brushes at David Kearney blog

Commutator Sparking Of Brushes. The most common cause of carbon brush failure is incorrect spring tension. Check holders for damage or dirt. If the sparks go all the way around the copper strips, also called the commutator, the armature has shorted. Uneven commutator contact surfaces can accelerate brush wear. All brush type motors have some brush sparking because you are breaking an inductive circuit with current flowing in it. It accelerates the rate of brush wear and damages. The one check you can easily do is to verify that there is at least a small. Check brushes for free movement within holders. Sparking is observed at the brushes: Vibration of the machine itself may cause brush sparking and eventually result in commutator damage. Blue sparks, brilliant and noisy, with burning, generally indicate a serious commutation fault ; Such vibration may be caused by imbalance in the armature, by poor foundations or other mechanical faults. It can also result from defective bearings.

Do these brushes and commutator look alright to you? It was sparking
