Opening up a compressor first time could take 5/10 minutes after you become proficient with the plasma maybe 2 minutes.Originally Posted by GeorgeB
Fortunately I'm not being paid by piece work.
In that picture I'm showing how i have split the nut using the plasma so that I may remove the halves allowing the pulley to come off. I need the armature shaft fee and clear when I tap the end of it to get the burnt wire off.
The commutator is the copper bars where the brushes used to ride fall right off once you remove one segment forceful the rest fall out. Large generators have mica between the coppers for insulation. When working on one of these it is best to work on a tarp, makes clean up much easier.
When I get around to the electric motors, again I will post pictures with comments.
Split nut on old generator from either an automotive application or tractor, pre alternator.
On a side note, a generator will charge a stone dead battery while an alternator will not. A generator can become non functional after sitting for years or being dropped.
The residual magnetism will leave, then you have to polarize the generator to get it working again.
An alternator needs a trickle of electricity to excite it into charging,but is able to sit idle for years and still work.
