Got it Stan !  I just didn't understand your use of the word "wear".  Yes, motor manufacturers try to make electric motors more job specific to save mfg. cost. There used to be more of a "one size fits all" era.   Recently I bought a used   Baldor 2hp,  220v motor on Ebay. It had slightly noisy bearings so I decided to replace them plus inspect and clean the inside in the process.   Bought a pair of good US made bearings.  The inside of that Baldor was a work of art. Totally brushless, the armature was solidly made and insulated such that I could hardly see the laminations. The field windings were heavily varnished along with the paper and bakelite separators. Since it is a sealed motor housing, there was very little dirt and debris inside so cleaning was easy. I replaced the bearings and reassembled it and plugged it in.  It was flawless and quiet !  I could have bought a new motor for $100 + at Harbor Freight or Rockler  etc. or buy a new Baldor for $500 or so. I went differently and bought the used Baldor on Ebay for $94.00 plus $17.00 for a couple bearings. Why ? The inside of a  Baldor is extremely well built and should last forever (bearings excepted).  I guess thats why they cost around $500 new. Finally, I'd guess that the used motor I bought is more than 30 years old.........Bruce
