Direct current motors (DC motors) are more difficult to repair due to the commutator-brush assembly. Let's look at what makes up the price of repairing a DC motor.
What complicates the repair of a DC motor
- Collector unit - requires grooving, pathing, maintenance.
- The armature winding is more difficult than the stator winding in rewinding.
- Brush unit - replacement and lapping brushes.
- The excitation winding is a separate element.
What makes up the price
| Work | Impact on the price |
|---|---|
| Commutator groove | Medium |
| Rewinding armatures | Main article |
| Replacement of brushes | Low |
| Repair of field winding | Depends on damage |
Repair versus replacement
DCFs are often more expensive and less commonly sold than asynchronous ones, so DRV repair is almost always more profitable than replacement. This is especially true for machine-tool and special engines.
The exact cost is announced after diagnostics of the commutator, armature and field winding. Regular maintenance of the brush assembly reduces the need for expensive repairs.
