Question: Armature Verse Fields?

rlvirant

The armature is 'arching' very badly.
That Com Bar is high the rest are OK.
Open or Shorted turn cause this?
Applied DC to fields - from a 15vdc supply - and from that it appears that both create same mag field. Ran it on 15vdc and armature still arch's.
Hi rlvirant,
Generally what causes this is heat issues.The temp get high enough that the laminates start to break down. If the field and armature winding looks the color of dark red or purple its a sign of a heat problem.You would then need to replace both the field and armature to do a clean repair. Hope this helps.Good luck.

The field has NO dis-coloration. The armature windings are alittle more difficult to detect. In this case the arm windings are poorly wound - loose. The epoxy didn't bind the individual windings inplace. Heat? maybe but question remains Open or shorted turn? I soldered the supected turm at the riser but didnt' help - if open - it should have lessened the arching NO?
I do work with industrial motors(frac to 5000hp) Reliance Electric so I have a good basic understanding of a DC motor but not enough to get thru this one. That's when I call a motor expert.
Still need some guidance.
Question: Armature?

Ok so I was using my dewalt dw871 the other day and the all of the sudden it lost power and started smoking and sparking at the brushes. I took the brushes out and they looked good as well as the springs holding them in. So I shined up the armature where the brushes make contact, reassembled and still the same. Will a new armature fix the problem or is the field suspect as well? One or the other would be worth replacing but probably not both. What is the general concensus? Any input would be greatly appreciated.

Cut-off saws, as do other power tools get a good work out when they are used, and under heavy loads the motor will get hot and eventually breakdown the insulation on the windings of the armature and field causing them to short out. Look again at the armature to see if any of the commutator bars are discolored or raised up higher than the others. If so replace the armature. If not, it's sometimes a tough call to tell if it is the armature or field are bad. Most qualified repair shops will have a piece of test equipment in the shop called a "high-pot tester" in their shop to test the parts in question. You might ask one to test your parts.

Good luck,
