INSPECTION
1. ARMATURE
1. Check the commutator for signs of seizure or stepped wear caused by roughness of the surface. If there is light wear, use sandpaper to repair.
2. Runout test Check for runout on the commutator. If excessive, replace it.
3. Depth of segment mold
Check the depth of the segment mold.
4. Armature short.circuit test
Place the armature on the growler tester to check for short circuits. While slowly turning the armature, support the steel sheet for the armature
core. If the circuit of the armature is shorted, the steel sheet will vibrate, causing it to move towards the core. When the steel sheet has moved
or vibrated, replace or repair the armature with the shorted circuit.
