Commutator motors are reliable, but require regular maintenance of the brush-commutator assembly. Let's look at how to properly care for a commutator motor.
Brush control
Brushes are a consumable item. They need to be inspected regularly:
- Check the degree of wear (length).
- Monitor the fit to the commutator.
- Monitor the force of the pressing springs.
- Replace worn brushes in a timely manner.
Cleaning the commutator
The commutator becomes contaminated with carbon dust from the brushes. It is periodically cleaned, and when produced, it is sharpened and valued. A clean commutator is the key to the absence of sparking.
Signs of problems
| Symptom | Cause |
|---|---|
| Sparking | Brush wear, dirt, wear |
| Blackening of the commutator | Contamination, poor contact |
| Rapid wear of brushes | Depleted commutator, vibration |
When repair is needed
If the commutator is worn out or sparking is not eliminated by replacing the brushes, repair of the commutator unit is required - grooving and path. If the armature winding is damaged - rewind. The condition will be assessed by diagnostics.
