MCS can be pared with a maintenance contract where a yearly "clean & sweep" of the motor and its components is conducted. The motor is temporarily taken out of service during the procedure and the motor can be quickly put back into service if needed.
- Surface of the commutator is stoned to restore a more uniformed surface, mica undercut and the copper bar edges chamfered to reduce brush wear.
- Electrically test the armature, field coils and inter-poles.
- Using a small high speed blower, compressed air and nitrogen the coils of the armature are blown out to remove carbon that has accumulated over time.
- Clean and remove debris from the entire machine (loose paint, broken insulation, grease and carbon dust).
