Visual Inspection of Armature and Commutator
Some defects can be seen by examining the armature and commutator. Defects seen during the visual
inspection can aid in diagnosing the original cause of the failure. Items to look for are listed below.
• Burned, charred or cracked insulation
• Improperly cured varnish
• Thrown solder
• Flared armature windings
• Worn, burned or glazed commutator
• Loose or raised commutator bars
• Bruised or damaged armature core laminations
• Worn armature bearing or shaft
• Dirty or oily commutator
Commutator Cleaning and Inspection
1. Clean the carbon dust, dirt and oil from the commutator. Slight roughness of the commutator can be pol-
ished away with 400 grit (or finer) sandpaper. See following CAUTION .
CAUT ION
• Never use emery cloth on the commutator. Particles of emery are conductive and may short-
circuit the commutator bars. Never use oil or lubricants on the commutator or brushes.
2. Use a micrometer and measure the outside diameter at four points: two points 90° to each other to the
outside end of the commutator (A
1
and A
2
), and two points 90° to each other to the inside of the com-
mutator (B
1
and B
2
). If the commutator diameter is less than 1.535 inches (39 mm) at any of the four loca-
tions, replace the armature assembly and bearings (Figure 12-11, Page 12-7) .
